[sage-support] Strange

[Henri Girard]

I made this graph (meaning a fano's plane) but I have the zero outside 
the graph ?


I don't understand why ? someone could explain ?

My adjacency_matrix is 8 but shouldn't be 7 ?

g=Graph(7)
edges = [(1,2), (1,3), (1,4),
    (2,3), (2,4), (2,5), (2, 6),
    (3,4), (3,5), (3,6), (3,7),
    (4,6), (4,7), (5,6), (6,7)]
g.add_edge(1,2),g.add_edge(1,3),g.add_edge(1,4),g.add_edge(2,3),
g.add_edge(2,4),g.add_edge(2,5),g.add_edge(2,6),g.add_edge(3,4),

Re: [sage-support] Strange

[Henri Girard]

thanks, I tried david suggestion and it's correct now :

edges = [(1,2), (1,3), (1,4),
    (2,3), (2,4), (2,5), (2, 6),
    (3,4), (3,5), (3,6), (3,7),
    (4,6), (4,7), (5,6), (6,7)]
Gamma = Graph(edges)
Gamma.show()


Meanwhile I made it too with networkx to compare :

import networkx as nx
import matplotlib.pyplot as plt
G = nx.Graph()
edges = [(1,2), (1,3), (1,4),
    (2,3), (2,4), (2,5), (2, 6),
    (3,4), (3,5), (3,6), (3,7),
    (4,6), (4,7), (5,6), (6,7)]
G.add_edges_from(edges)
nx.draw_networkx(G)
limits = plt.axis('off')
plt.show(G)

Graph? shows

  2. "Graph(5)" -- return an edgeless graph on the 5 vertices
 0,...,4.

  3. "Graph([list_of_vertices,list_of_edges])" -- returns a
 graph with given vertices/edges.

 To bypass auto-detection, prefer the more explicit
 "Graph([V,E],format='vertices_and_edges')".

  4. "Graph(list_of_edges)" -- return a graph with a given list
 of edges (see documentation of "add_edges()").

 To bypass auto-detection, prefer the more explicit "Graph(L,
 format='list_of_edges')".

  5. "Graph({1:[2,3,4],3:[4]})" -- return a graph by
 associating to each vertex the list of its neighbors.

 To bypass auto-detection, prefer the more explicit "Graph(D,
 format='dict_of_lists')".

so it seems correct, and there are alternatives if you prefer 1..8 
instead of 0..7.

Jan

Re: [sage-support] Right way to kill notebook server on single-user machine

[Henri Girard]

Le 17/04/2018 à 05:53, Tevian Dray a écrit :
I'm a relatively new Sage user, trying Jupyter for the first time.  OS 
is Ubuntu 14.04; Sage version is 8.1.  Starting Jupyter from the 
command line (sage -n jupyter) works as expected, but so far as I can 
tell the only way to shut down the notebook server after closing the 
browser is via ctrl-c.  What if sage is not started from a terminal? 
 Or if stdout is redirected to a file?  For example, if I redirect 
stdout when starting sage, then send ctrl-c after closing the browser, 
the sage-notebook process continues to run -- presumably because I 
have no way to send a second ctrl-c.


I found this 10-year-old post asking essentially the same question:
https://groups.google.com/forum/#!newtopic/sage-support/sage-support/IrA6obQupKw
but parts of it are clearly out of date.  However, the suggestion to 
use "kill -2" sounds promising, but on which process?  I only see two, 
one running sage-notebook, the other running sage-cleaner.  Or is 
there some other way?  "killall python" works, but presumably isn't a 
clean shutdown -- and I certainly wouldn't want to script such a 
sledgehammer.


It would be really nice if there were a provided script for shutting 
down the notebook server cleanly!

Thanks for your report! I edited the interact page
of the Sage wiki, adding links to the documentation:

- interacts in the Jupyter notebook

http://doc.sagemath.org/html/en/reference/repl/sage/repl/ipython_kernel/interact.html

- interacts in the legacy SageNB notebook

It has its merits, but it is no longer developed;
one could say it is in low maintenance mode.

I don't know.

Good idea. All the notebook development effort now goes
to the Jupyter notebook.

So it looks like even if you just sudo apt install tk8.6 (and
mabye tk8.6-blt2.5??)
your ubuntu python might pick it up but not the sage python.

So you should sudo apt install tk8.6-dev (and mabye tkblt-dev??)
and then rebuild the sage python as per the instructions at
the link above.

tk packages in ubuntu 18.04:


https://packages.ubuntu.com/search?keywords=tk&searchon=names&suite=bionic§ion=all

Or perhaps there is someone else who can answer if one can
tell Sage not to try to use tk for
show(lines(... but to use another graphics toolkit.

[sage-support] nabla (levi-civita tensor of g)

[Henri Girard]

hi,

I would like to use nabla as div or grad operator, in sagemanifolds it's 
used as levita-civita, how could it be use as them if it's possible ?

Can you give an example of what you would like

Yes...

nabla.E=rho/epsilon (maxwell 's equation)
but in latex

sage_for_undergraduates_color.pdf  page 137

I often use symbolic expression to remenber the equation, then I use it 
in sage


Another example :

http://nbviewer.jupyter.org/github/sagemanifolds/SageManifolds/blob/master/Worksheets/v1.3/SM_vector_calc_cartesian.ipynb

grad(F)=∂f∂xex+∂f∂yey+∂f∂zez

Instead grad I would like nabla (but in sagemanifolds nabla is used as 
levita connection) then I dont know yet how to use it ... But I don't 
desperate to find it one day :)


Δ(w)=0la

laplacien
http://nbviewer.jupyter.org/github/sagemanifolds/SageManifolds/blob/master/Worksheets/v1.3/SM_Kerr_Newman.ipynb

∇gg=0

The Levi-Civita connection ∇associated with g:

I would like to use it as nabla operator for grad and div

I hope I am clear enaugh (not very easy as I don't know it well)

Re: [sage-support] How to use sage's macaulay2 interface in jupyter

Re: [sage-support] algorithme

\ can be used when one wants to slip a line , in a long line

for example

plot(sin(x),x,0,2, color="red",figsize=3,

in fact here is not really useful it's just for the example, because in

Good day,
I am a very new user of sagemath.  I am mastering independent operations.  My 
trouble is on the level of algorithms.
So far, I cannot understand how to program with sageMath (see the screenshots).
Thanks for helping me to get started.

The problem is the use of “\”.  Python programs are structured by indentation, 
so the way to type the program in an editor, at the command line prompt, or in 
the notebook, is as follows:

def fac(n):
 if n == 1:
 print ‘bonjour’
 else:
 print “bonsai”

The OP was entering the code almost correctly, but the “\” caused the parser to 
ignore the new-line, and string everything together as one line.

Vous devriez tenter de comminuquer en anglais, qui est la langue
comprise par le plus grad nombre (de loin) de lecteurs du groupe.
Après tout :
sage: r.library("fortunes")
sage: r('fortune("Bad English")')

Bad English is the language of science.

Cela dit, je ne saurais trop recommandé la lecture du remarquable
manuel collectif "Calcul mathématique avec Sage
", qui décrit (en français, s'il
vous plaît...) une version un peu ancienne de Sage, sa traduction
anglaise , qui
utilise une version plus récente, pouvant également vous servir de
pierre de Rosette ...

Vous aurez aussi besoin d'un manuel pour Python, pour lequel je ne
me sens pas apte à faire une recommandation. Notez que Sage
utilise actuellement Python 2 (en voie d'obsolescence), mais
migrera prochainement vers Python 3.

Hi,
I am working with Menny Aka and Tom Ward on a little book for high

We are also new to sage but really enjoyed learning it along the
way. Thanks for the great tool.

During the refereeing process we were told by one of the referees
of the upcoming python 2/3 change and that it would be annoying if
our intro to sage is obsolete even before the book gets published.
 I haven’t yet tried but I will download and install the latest
beta on version 9 to test all sage code in our book. Is there
anything I should be a aware of when I do? Eg. to what extent is
it complete — I believe our little intro doesn’t venture very deep
into the possibilities of Sage.

Thanks,

Re: [sage-support] tar jxvf sage-9.1-Ubuntu_18.04-x86_64.tar.bz2 is not downloading SageMath

If you check the results of this command, you will see what
the problem is:

 "tar jxvf sage-9.1-Ubuntu_18.04-x86_64.tar.bz2: Cannot open:
no such file or directory"

This means that the “tar” command is not able to locate the
file “sage-….” in the current directory.  You either need to
run this command in the directory containing the file, or give
the “full” file name to the command.

The first weirdness is that Sage can't compute the integral

The second weirdness is that the Taylor series is wrong!
Taylor(Si(x),x,0,10) gives the same answer.

I'm able to build Cadabra2 in SageMath environment (at sage --buildsh

on Debian Linux. This way it should be possible to use it with Sage's

But on Windows, well, probably much harder...

That only uses the Cadabra python module, which means that you do not 
have access to all the Cadabra specific syntax for declaring 
expressions and properties. Nothing wrong with that, but if you want 
the full experience, you need the Cadabra kernel (which in effect 
pre-processes the input before feeding it to Python).

I'm not entirely clear on when "Sage Worksheets" became Jupyter
notebooks. I think, when we started 5 years ago, that we weren't
aware of the switch; I certainly wasn't. I personally haven't
looked enough into the details and/or differences to write
intelligently about them.


Sage worksheets = a way of using Sage in Cocalc *ONLY* that involves a 
single codemirror editor document, and a really powerful way to easily 
define %mode's. It's very tightly integrated with Sage.   It's also 
written in a pretty old style (using a lot of html and jquery), and I 
plan to rewrite it soon, since it's one of the only things left in 
CoCalc that isn't written in Typescript/React.  Sage worksheets are 
implemented entirely separately from the Jupyter stack, not even using 
the Jupyter kernel for Sage (instead, they have their own backend 
server process, which uses fork each time  you make a new connection, 
for faster startup).  They do have a way to easily create any number 
of connections to different Jupyter kernels, and use them all in the 
same worksheet.   I wrote Sage worksheets mainly 2012-2014, and have 
maintained them ever since, because they are pretty popular on CoCalc, 
e.g., they just use a normal single document editor interface, rather 
than a "weird" modal interface with many little editors like Jupyter 
notebooks, and some people find the Sage worksheet approach more natural.
One nuisance of Sage worksheets is that the exact version of Sage 
isn't specified anywhere in the file format -- it just uses whatever 
"sage" is in your path. Jupyter is better in this regard.


Jupyter notebooks = of course we all know what they are.

I'm personally a huge fan of both, but they are very different.    I 
hope I can unify the two approaches sometime soon, so that there's a 
mode for using any Jupyter notebook that looks like a Sage 
worksheet... and so the custom Sage server mentioned above is just a 
different Jupyter kernel (maybe called "cocalc-sage").

Hi,

I just discovered wsl2/wslg windows native X support. GitHub -

I was wondering if someone already tested it ?

And the must tried to run sagemath with it ?

Any info will be best ?

I didn't not understand your question, I am french.

But I use show(LatexExpr(r" c'est  \ en \ français") ) for the text

show(LatexExpr(r" \sqrt x^2") ) for maths and I obtain nice things

Sorry for answering my own question.

It seems that

sage: P = Poset([[1,2,3,4], [[1,2], [2,3], [1,4]]])
sage: e = {i: LatexExpr("q^%s" % i) for i in P}
sage: c = {(i,j): LatexExpr("%s^%s" % (i, j)) for i, j in 
P.cover_relations()}


sage: H = P.hasse_diagram()
sage: [H.set_edge_label(v1, v2, c[(v1, v2)]) for v1, v2 in 
P.cover_relations()]

sage: H.relabel({v: e[v] for v in P})
sage: H.set_latex_options(format="dot2tex", edge_labels=True)
sage: view(H)

works.
Martin R schrieb am Dienstag, 2. November 2021 um 19:37:34 UTC+1:

is it possible to display a poset with (LaTeX) labels on the
covering relations and (LaTeX) labels on the vertices?

For example:

sage: P = Poset([[1,2,3,4], [[1,2], [2,3], [1,4]]])
sage: e = {i: "$q^%s$" % i for i in P}
sage: c = {(i,j): "$%s^%s$" % (i, j) for i, j in P.cover_relations()}
sage: P.plot(element_labels=e, cover_labels=c)

This almost works.  Unfortunately, the layout is not the dot2tex
layout, which I need because my posets are large, and it displays
'None' instead of the edge label.

[sage-support] gwsl2

[Henri Girard]

For those who want a running sagemath linux on windows 10/11 or amber20 
or any app not working on windows use gwls2 very easy to install 
(actually ubuntu 20.04 for me but I tried to upgrade to 22.04 (+1) and 
it works fine so I even have sage 9.4, I can't get any more for the 
moment on it !)


The detail help on microsoft help is suffisiant to install wsl2 and then 
get the gwsl2 on microsoft store with one click installation.


Sorry but I didn't know where posting this info for sage users

I am not sure that what you want (and naturaly first command in cell

One can even format text in a beautifull latex

show(LatexExpr(r"This \ is \ \mu \ and \ \epsilon"))

Le 02/02/2022 à 18:38, Sean Fitzpatrick a écrit :
I'm teaching a linear algebra course where we use the Sympy Python 
package for a lot of the computations. This includes a PreTeXt 
textbook where there are Sage Cells throughout, with sample code 
supplied.


Until today (I think it was working yesterday), I've had no trouble 
running code like the following:


from sympy import Matrix, init_printing
init_printing()
A = Matrix([[1,2,3,4],[5,6,7,8],[9,0,1,2]])
display(A.rref())

The init_printing function from Sympy renders the output in MathJax 
rather than pretty-printed plain text, which is nice for teaching. I 
can run this with the language set to either Sage or Python. (the 
'display' command is only needed for Python, which is funny, because 
it is not needed in Jupyter with a Python kernel.)


Right now this code throws about 50 lines of error messages; the main 
error is a Type Error:


TypeError: Object of type  with value of '(a very, very 
long string that I won't reproduce here)' is not JSON serializable


Was there a change made today that would cause this error? Maybe in 
the Sympy library? If I remove the init_printing() line, everything 
works, except that there's no longer nice display for the output.


The reason for using Python syntax is that we also do labs in Jupyter 
notebooks. Our institution has a Jupyter hub with Python and R 
kernels, but no Sage kernel. (We do not have a CoCalc subscription.)


I know there is a Sage equivalent to init_printing (although I forget 
what it is) but that won't work on the Jupyter side.

true researchers because everything is offered on a palette ! lol

I like sage because I can compile it, I tried all these years to buy a
better computer (every 5 years) to not spend days compiling. At the
moment my Rizen 16 cores with 16Go RAM, that's good.

Sorry for this email written in french/english but I can tell you carry
on this wonderfull soft !

Best regards

In fairness, "Mission: Creating a viable free open source alternative

What do Maple and Mathematica do regarding having a median top level command?

Also, if you want to argue that users should explicitly import
everything... that's an interesting an valuable challenge to support
and your modularization
work Matthias is of course critical to that.  However, it doesn't at
all preclude the default "sage" environment still being a viable
alternative to Maple and Mathematica.

But shouldn't these basic functions have some default functionality? Is the

Students (mostly) don't know what numpy is and makes using mean, median and

basic things that a student would use have names that might be in their

Will Calculus be deprecated too?

Re: [sage-support] Re: SageMath on Microsoft Windows

[Henri Girard]

Well... A little hacking if I dare say :)

Install wls2 with ubuntu 20.04 then install gwls2 with microsoft store 
verify it's working (it should) and then do-release-upgrade and it 
should install a kind of 22.04. I got it working with sagemath-9.4 (i 
don't know why it' not sage 9.5 as I have it working on a dual boot with 
ubuntu .


Why I do this ? because I have windows 11 and many softs like anaconda 
sage-math windows but yet I didn't success to install wolfram engine on 
windows but in gwls2 jupyter notebook mathematica works well only few 
backdraw but only cosmetic.


It's not too difficult but it needs patience because it can be tricky, 
but the result is good with mate-desktop I use. I even compiled amber20, 
sagemath but needs time.

I did find Ubuntu 20.04 binaries for SageMath 9.4 in

switch to the SageMath directory and type ./sage. That gives an error:

some Linux distributions have pretty much up to date Sage

E.g. archlinux has Sage 9.5. Thus, having it installed as
WSL2 (cf

By the way, has anyone tried https://www.wolfram.com/engine/ ?
We can think of making an interface to it, as it's a free and locally
installable.

Yes, yes, yes : easy comparison to Wolfram's (Mathematica's) result 
may be important in various contexts (and may offer a solution where 
none of Sage's tools works, e. g. various primitive search problems).


A "nice" presentation could be, like our current Mathematica 
interface,  a standard package compilable without Wolfram Engine 
having to be present on the target machine, giving an informative 
error message if called on a machine without the engine, but giving 
back the expected result if present.


The documentation should include (a pointer to) instructions on how to 
install the Wolfram engine.


That could revive my log of untranslatable Mathematica results, for 
which I have some proposals (but didn't bother to formally file, since 
enhancing access to a non-free product may not be a priority...). If 
something gratis, not (too much) encumbered and not-too-hard to 
install  can  be obtained without too much hassle, that should become 
a priority.

Does system-wide jupyter (apt-get install jupyter) package work for

If it doesn't, then the problem has little to do with Sage.
(and probably you'd need to fiddle with your Firefox security settings)

If it does, you can use it to run Sage notebooks

jupyter kernelspec install

Re: [sage-support] Availability of sage 9.6 through conda/mamba?

[Henri Girard]

Is the conda sagemath working on windows ?


Le 12/07/2022 à 11:21, Julian Rüth a écrit :

Hi Joseph,

thanks for the notification. We had simply forgotten to update the sage
package. We are now in the process of providing the sage 9.6 package for
conda-forge at https://github.com/conda-forge/sage-feedstock/pull/77.

* Joseph Nasser  [2022-07-11 11:54:04 -0700]:

Is it possible to install sage 9.6 through conda? If so, how?

In the meantime, you can install a (hopefully mostly functional)
SageMath 9.6 by installing sagelib 9.6 into a sage 9.5 environment,
e.g.,

mamba create -n sage96 python=3.10
conda activate sage96
mamba install --only-deps sage=9.5
mamba install sagelib=9.6

You might have to replace mamba with conda if you don't have mamba
installed.

Hi all,

I'm trying to run sage on WSL2 (Ubuntu focal 20.04.5

9.0), running `sage` gives the following error.

ModuleNotFoundError: No module named 'sage.cpython.string'

I happen to know that the packages are installed
in /usr/lib/python3/dist-packages/, and
sage/cpython/string.pyx is in there.

What's particularly strange to me is that sage
/can/ find `sage.misc.banner` (which is in the same
dist-packages location). Meanwhile, I can run `sage
-python` and inspect `sys.path` manually (it has the
right dist-packages path in it), but importing
sage.all in that context fails with
"ModuleNotFoundError: No module named
'cysignals.signals'" and similar with other imports.

I understand the recommendation is to use conda or
build from source to get a version > 9.2, but is there
a quick fix I can do to link the sage-python to these
libraries? Maybe an existing trac issue I can read
through workarounds? The reason I ask is because I'm
working on a library that uses sage and it's a bit of
a pain to fire up docker (and worse, the sagemath
docker image had known issues (only just now seeing

that a new docker image got pushed; still, working in
docker is a bit inconvenient))

Any ideas? Further steps for investigation?

def f3d(figure, **kwargs):
    return make_frame3d(figure, **kwargs)

I have done a pic included

Some time ago it sounded in the list that this fonction could be 
integrated to sage ?


Is there any work done in this direction in sage 10 ?

looks like you need to install an extra package here.
Try doing

   sudo apt install libomp-dev

and then run

   make

again. You've probably run into this, as we don't test clang on Linux,
as far as I know.

In SMC, create a jupyter notebook just like the one in your link.
Add an extra cell at the beginning, containing

%load_ext sage

and everything should work.


Well, except graphics don't get displayed, which of course matters here.

The Python 2 kernel and `%load_ext sage` only get you so far,
but still it's worth mentioning that setup does give some usability.

There are a few tutorials of sorts people have done on their own, but 
they are less comprehensive.  If you have something a little more 
comprehensive, PLEASE by all means contribute it!   Especially if 
there is a part you can add to the plot/graphics documentation itself, 
or where we can do a link within the documentation to your tutorials. 
 I agree that this is all sort of spread throughout documentation and

Don't you think we should start by doing the same for Sage's own source

debugging/maintenance of what (s)he added for the next 5 years? Looks weird
to only have this high level of expectation for third-party code only, and
not for our own.


Hey I was just reporting on a conversation with Guido about what they
*already* do with Python.


In Sage, we are at a level where some files don't have a clear "regular
maintainer". We would need to be 10x more developpers to enforce such rules.


Indeed -- Python probably has 10x more developers...  maybe someday we
will have way more developer time too.  We don't now, as we are
massively under-resourced.


For 'cliquer' in particular, maybe we could propose upstream a autotoolized
build system, and see how it goes? We did it for 'planarity' not so long ago
(and perhaps with others?). Our spkg-install file indeed contains several
platform-specific instructions.

Huge +1.  I'm all for Sage devs contributing upstream :-)

Re: [sage-support] Re: Sage 7.0 crashes

It means your sage hasn't openssl you probably can use pip ?
sudo pip install ssl (or something else on mac)
I am on linux not on mac.
./sage -n=ipython is the command I use...
Time being I am not sure it is so clear with "notebook, jupyter, ipython"
I had to slightly hack to get everything working and I don't even 
remenber well what I deed as my config is working but if I break it I 
probably have to search again.
I like sagenb (sage -n), because the editor is quiet well 
fournished. But it's more difficult to make all things working... I mean 
use all pythonize things...

Re: [sage-support] Re: Sage 7.0 crashes

[Henri Girard]

Hi
I don't agree with what you are saying...
There are so many examples : google search I do... sagemath /pub/sws
And most of all sagenb server in the world will show to you !
With ubuntu it was quiete easy (I compiled it now, on ubuntu it's very 
easy), I just discovered jr Johanson ipython notebook which are even 
working on sage 7 now !!!
What an improvment : I used to try few years ago and they didn't work 
but now with sage -n=ipython they work mostly fine, just some correction.
And last but not the least : Nothing to pirate ... I tried mathematica, 
maple, I think they are gaz machines ! lol
I could tell you more, but just keep searching and look at mailing 
list... I discovered few days ago how to connect ROOT Cern to jupyter... 
and much more.
I am old and I haven't much time to make a collection of all what I have 
done, but my kids are young and I am preparing notebooks in french to 
help them. why not use sagemathcloud too ? For me that was a revelation 
because sagemath wasn't working on windows (except in V env)
I guess for someone coming from mac it might be more difficult but linux 
is a kind of mac, my theme is macbuntu theme ! lol
Kind regards and keep on sage :) specially now with both sagenb and sage 
-n=ipython. I can tell you I am not an expert ! But It's my hobby so I

True... These days I am discovering so many python ipython jupyter good

sage sagemanifold ipython and many others, visit ... The list is long !

But the problem is how to get money to found this.

The community of mathematicians and math teachers have so far chosen
to financially (and otherwise) support Sage at about 0.01% of the
level that they support Mathematica.  I fear that you do not know who
writes Sage, where Sage comes from, or how it is funded.

Until the mathematical community is willing to support -- in real ways
(money!) -- open source math software, they are very naive to expect
the same level of polish for the masses that can be provided by the
effort of thousands of employees (which Mathematica and Matlab
collectively have).

Much open source volunteer work is currently massively under
appreciated and this is one of the biggest mistakes of society of this
decade.

What you say is true, of course. But perhaps the lack of money is not
the guilty of mathematicians and math teachers, but of the persons
and organizations that decide the funds for research.

In any case, this does not change the problem: students do not like to
use sage.

Unfortunately, this is the truth.

Re: [sage-support] sagemath 7.0 installation time on Ubuntu 14.04

[Henri Girard]

I installed it yesterday and had the same surprised (maybe shorter 
patch) after I installed sagemanifolds successfully a bit slower than 
6-10 but still suiting.


Le 03/02/2016 18:43, Graham Gerrard a écrit :
Recent installation of Linux binaries on Ubuntu now takes much longer 
than a few versions ago.  Binary unpacks, no problem.  After linking 
to the new version in /usr/local/bin, the first run of sage initiates 
a large amount of time consuming checking and updating, used to be a 
minute or 2, now at least 30.  All OK, after a suitable wait.


Installation of an additional package (in my case, database_gap) using 
"sage -i database_gap", initiates another automated collection of 
(>500) steps, which eventually results in a successfully install. 
Similar wait. Again successful.


I can install a similar gap database by unpacking an older version, 
e.g. database_gap-4.7.7.tar.bz2 and copying the bits into the right 
place in the GAP directory. Very much quicker (and seems to work).


Is this longer installation time to be expected in the future? Am I 
doing something wrong?

explicit(if x < 0 then sqrt(-x^^2 -2*x) else -sqrt(-x^^2

But I need it in sagemath to get it well embedd in texmacs.
After long trying I didn't not success, my main problem is
conditions.
If a good soul could do it for me all my thanks.
Kind regards,
HG

I have done this which is not really good :
y=sqrt(4-x^2);b=y
r=sqrt(-x^2-2*x);q=-sqrt(-x^2+2*x)
e=solve(b==r,y)

c=plot(b,(y,-2,2),fill=True,fillcolor="black",color="black",figsize=3,aspect_ratio=1);

c+=plot(r,(y,-2,2),fill=True,fillcolor="red",color="red",figsize=3,aspect_ratio=1)

d=plot(-b,(y,-2,2),fill=True,fillcolor="red",color="red",figsize=3,aspect_ratio=1);

d+=plot(-r,(y,-2,2),fill=True,fillcolor="red",color="red",figsize=3,aspect_ratio=1);
p=plot(q,(y,-2,2),fill=True,fillcolor="red",color="red",figsize=3);
p+=plot(q,(y,-2,2),fill=True,fillcolor="black",color="red",figsize=3)
plot(c+d+p,figsize=2,aspect_ratio=1,axes=False)

Is this in sagenb?


Yes.

 I can confirm this works for me in 7.1.beta3, though I do have LaTeX 
installed. In the server I have access to with 6.9 I get this.  6.5 
on my computer works fine, so I *suspect* it is related to the LaTeX 
on the server somehow.  But maybe there was something that was wrong 
and fixed in short order in Sage itself?


Can it relate to server_pool -option? With a slight misconfiguration 
one can get SageNB where sin(0) works but plot(sin) does not.

What box?

But now I tested "Typeset" box. It works, so LaTeX installation is OK. 
And for example %timeit works, so %-string works. Strange.

I have just requested a copy on launchpad. Should be ready in an hour.

Note the difference though: 
http://files.sagemath.org/linux/64bit/index.html has binaries from the 
sage buildfarm built on 14.04, 14.04, 14.10, 16.04 with the toolchain 
from that release. Yakkety is not yet included.


Only 14.04 is rebuilt into a PPA, and on launchpad the 14.04 
binary/deb is copied forward to 15.04, 15.10, 16.04 (and now 16.10). 
So far no problems, but if you run into problems you may want to 
download and unpack the 16.04 binary which is much closer to the 
toolchain version of 16.10 than the 14.04 binary.


Regards,
Jan

Re: [sage-support] jupyter lab

Thanks it works after changing few things like path etc, my sage 
kernel.json is :


{"display_name": "Sage 7.2","argv": ["/usr/lib/sagemath/sage","-python", 
"-m","sage.repl.ipython_kernel", "-f", "{connection_file}"]}


I use sage repo with sagemanifolds. I guess I will soon update to 7.3.

Thinks evoluate (beautifully) lol

I think jupyterlab is a promising project. For me I can collect all

THis is the first time I heard about jupyter lab ! (things evoluate very

need to add "kernels" for the different language/applications I want to
run. They go in /usr/local/share/jupyter/kernels.
Exemple:
/usr/local/share/jupyter/kernels/sage

"-m", "sage.repl.ipython_kernel", "-f", "{connection_file}"]}

Hi,
I don't know how to make a toc of sagemath workshit

Can you clarify?

   (1) I assume you aren't trying to be insulting by saying "workshit".
   (2) Are you talking about sagemathcloud or sagenb or jupyter?
   (3) What's an example?


Kind of index.ipynb with a link to different notebook.
