[sage-support] Re: Sage 4.7.2 make failure on Thinkpad T-40 with Oneiric Ubuntu

[Keshav Kini]

The error message you see at the end of a failed build directs you to post 
to sage-devel, actually, so I guess it's supposed to go there.

[sage-support] Re: Installing latest sage

[Eric Kangas]

The testall function finished earlier then expected. I did have only
one time out error. The error listed:
-
The following tests failed:


sage -t  -force_lib "devel/sage/sage/sandpiles/sandpile.py" # Time
out
Total time for all tests: 19977.9 seconds
Please see /home/nooniensoong97/.sage//tmp/test.log for the complete
log from this test.
-

Is there a way to fix these time out errors?

Explanation. I have a row of 7 rationals pq (in QQ), and I construct
aan VanDerMonde matrix (en.wikipedia.org/wiki/Vandermonde_matrix). The
row always contains [0,-1].

nulkern=matrix(xplusy_macht+_sage_const_2 ,xplusy_macht,[[pq**i for i
in xrange(xplusy_macht)] for pq in
breuken]).integer_kernel().basis_matrix()

I try to find the integer_kernel of the 7 by 5 matrix. Related is the
question on ASKSAGE ask.sagemath.org/question/941/is-there-a-routine-
to-find-a-integer-base

This is sufficient? I can rerun the calculations to find the hot spot,
but that will take a few days.

[sage-support] Re: [sage-devel] Re: Sage 4.7.2 make failure on Thinkpad T-40 with Oneiric Ubuntu - maxima fails to build

[Dima Pasechnik]

Well, welcome to the bleeding edge development. :)
Oneiric is not currently supported by Sage, as you probably know. 
No, it's not something to do with debian packages, it's most certainly 
Sage's internal issue.
It could be an unusual combination of rather dated hardware and  very new 
OS release that 
causes this --- i.e. noone tests on such systems, hence the problem.

Please post a complete install.log somewhere (not here in the group, 
preferably to a webpage)

There was a report in this group of a success in installing Sage on Oneiric 
by using gcc-4.4 instead of gcc-4.6:
https://groups.google.com/d/msg/sage-devel/aL8b9phz3Xc/FKnKiihV3SMJ
Perhaps it's a way to go for you.

Thanks very much, it works perfectly! I did not think of searching for

Well, if you have a formula for the nth coefficient of your series, you
can try using the ratio or root tests: 

x, n = var('x n')
a(n) = x^n   # formula for the nth term

[sage-support] Tests for convergence

[Ignas Anikevicius]

Dear list,

I like sage a lot and I want to use it a lot as well, but sometimes my
ignorance of the abilities of SAGE does not let me do that. I was
wondering if there is any way of running convergence tests for
infinite series in SAGE?

Cheers,
Ignas A.

It sounds like you don't have the current directory in your PATH.  You could 
try specifying the directory explicitly like (assuming you are in the sage root 
directory):

./sage -testall

Well for some reason when I am in the sage directory using the
terminal I try calling up sage, and sage - testall this is what I get:

No command 'sage' found, did you mean:
 Command 'osage' from package 'graphviz' (main)
 Command 'save' from package 'atfs' (universe)
 Command 'page' from package 'tcllib' (universe)

However I am able to run Sage in Cantor without any problems. I take
it sage is still building itself as I type this message up, or do you
mean when I run sage -testall?

Try this:

sage: var('x',domain=RR)
x
sage: var('k',domain=RR)
k
sage: exp(i*x*k)
e^(I*k*x)
sage: exp(i*x*k)*exp(-i*x*k)
1


The assume() system is from maxima. Unfortunately, basic arithmetic with
symbolic expressions doesn't know about these. It uses a different
system as you can see.

There must be a ticket to make these two assumption systems play nice,
but I can't find it ATM.

Hi! I'm working with an expression involving imaginary exponentials and their

Does it helps ?

sage: x=var('x')
sage: assume(x,'real')
sage: a=exp(I*x)
sage: a.trig_simplify()
e^(I*x)
sage: a.real_part()
e^(-imag_part(x))*cos(real_part(x))
sage: a.real_part().simplify_full()
cos(x)

Often making
a=a.real_part().simplify_full()+a.imaginary_part().simplify_full()
helps.
(maybe simplify_trig can replace simplify_full)

At my place I have
sage: b=a*a.conjugate()
sage: b
e^(I*x - I*conjugate(x))
sage: b.simplify_full()

[sage-support] Evaluate real variable subtraction with same variable conjugate to zero

[jrodri14ii]

Hi! I'm working with an expression involving imaginary exponentials and their 
conjugates:

exp(i•k•x)

exp(i•k•x)*=exp(-i•k•x)

 However, when multiplying them together, I do not get the arguments to 
evaluate to zero. My variables x and k are real, and I've told sage to assume 
that they are real. But it will not evaluate:

exp(i•k•x)•(exp(i•k•x))*

as:

exp(i•k•x+(i•k•x)*)=exp(i•k•x+(i*•k*•x*))=exp(i•k•x+(-i•k•x))=exp(i•k•x-i•k•x)=exp(0)=1.
 

Any ideas?

Thanks!

Do you think you could run

sage -testall

if you have a few free days to let your tablet just sit?  That could
