[sage-devel] Re: Problem with coercion of Laurent polynomials
We probably should be smarter about this in LaurentPolynomialRing by checking if the denominator is a monomial and converting the numerator into the (Laurent?) polynomial ring.

[sage-devel] Sage and Maxima get this integral wrong
There is an integral which Sage correctly numerically integrates, and which Sage symbolically gets very wrong. William and I looked into this during Sage Days 68, and he discovered that, in fact, Maxima gets this integral very wrong as well. (More correctly, the particular configuration and version of Maxima built into Sage gets the integral very wrong. Some setting might be incorrect or badly chosen.) The integral of sqrt( cot(x)^2 ) dx for pi/4 x 3pi/4 is not too bad to compute by hand. The answer is the logarithm, base e, of 2. The numerical integration in Sage agrees. Maxima thinks that the answer is instead zero. (Or more correctly, the particular configuration and version of Maxima built into Sage thinks the answer is zero.)

[sage-devel] Re: Sage and Maxima get this integral wrong
This is a typical ill-posed problem resulting from the limited mind-set
that comes from
thinking that sqrt is a single-valued function, and that therefore
sqrt(z^2), an expression which can be reduced to a set: {-z,z} should be
collapsed to abs(z).
Which it of course is not. Draw the graphs of f(z)=-z or f(z)=z, and
you see
that NEITHER ONE is the same as f(z)=abs(z).
So, given the very strong possibility that the limited mind set occurs in
at least one of 3 places:
the mind of the proposer
the mind of the Sage programmer
the mind of the Maxima programmer
what is one to do?
Do you want to integrate cot(z), which indeed gives an integral of 0,
correctly.
or do you want to integrate -cot(z), which of course also gives 0
or abs(cot(z)) which would be integral(cot(z),z,%pi/4,%pi.2) -
integral(cot(z),z,%pi/2,3*%pi/4).
and that gives log(2).
in the Maxima I have on my computer, integrate(abs(cot(z)),z,%pi/4,
3*%pi/4) gives the very
peculiar answer log(-1)
the numerical integration program quad_qag gives 0.69314718055995 which
looks like log(2).
So there is probably no bug in the integration version of the answer that
is 0, There is a bug
in sqrt. Or rather, in the mind-set regarding sqrt.
There is a bug in the integration of abs(cot()) though. probably related to
Nils' observation, though
probably not in the way he thinks... the integral is of a real function
between real values.
Also if Sage translates a definite integration to a call to Maxima for an
INdefinite integration,
and then using the fundamental theorem of calculus (difference of value of
integral at endpoints)
it is making a BIG MISTAKE. FTC doesn't always apply, and Maxima knows
something about
definite integrals, contour integration etc. Not apparently bug-free..

There is an integral which Sage correctly numerically integrates, and

during Sage Days 68, and he discovered that, in fact, Maxima gets this
integral very wrong as well. (More correctly, the particular configuration
and version of Maxima built into Sage gets the integral very wrong. Some
setting might be incorrect or badly chosen.)
The integral of sqrt( cot(x)^2 ) dx for pi/4 x 3pi/4 is not too bad to
compute by hand. The answer is the logarithm, base e, of 2. The numerical
integration in Sage agrees.
Maxima thinks that the answer is instead zero. (Or more correctly, the
particular configuration and version of Maxima built into Sage thinks the
answer is zero.)
Please see the attached sagews worksheet.
Is there anyone on this list who knows Maxima in general, and the
connections/interface between Maxima and Sage in particular?

But I thought that old-style packages were still available via sage -i, just that we'd be slowly moving to pip and/or new-style, so this is news to me. Dima, do you think the latest beautifulsoup would not change anything in the parsing from whatever version we have/had as an optional package? I don't have a problem having the instructions change to the sage -sh and pip install, this is a fairly high-level thing anyway. -- You received this message because you are subscribed to the Google Groups sage-devel group.

[sage-devel] Some documentation tickets
Those interested in documentation might want to look at few tickets. 1) Nathann is making an automatic index of functions better, see http://trac.sagemath.org/ticket/19061 . (But somebody should review #19067 before that will continue. It is short.) 2) There is a discussion about guide to writing docstrings: http://trac.sagemath.org/ticket/19041 . For example do we want to *always* have INPUT and OUTPUT section, even if the function returns nothing and have no arguments? 3) And then it is still open if the index of functions can be written from user perspective, or from implementation perspective: http://trac.sagemath.org/ticket/18534 . My suggestion one is adding functions from categories to index of posets.py. Suggestion two is add an index of functions ta categories of poset and finite poset and add a link to them. Suggestion three is to make a kind of introduction to finite posets and put index there. * * * 4) Do others feel that Sage is like a big house with tresures hidden in the corridors - without map to found those? -- Jori Mäntysalo
[sage-devel] Re: What are catalogs (groups.tab, matrices.tab) supposed to contain exactly?
To sum up, I would put a class/function in the respective catalogue if: 1) It's polished as in nicely callable by the user in a Sage session. 2) It's reasonably useful for people interested in the field of the catalogue. 3) It's not imported in the global name space. I tend to disagree with point 3. In the case of designs, we have some objects (the old ones) available in the global namespace, and some others (the more recent ones) which are not. It woud be messy to have some of them in the catalog, and some others in the global namespace. If some must be put inside of the catalog, then let it be all of them. Yeah, I see the point. Number 3 was to avoid having the super-generic constructors like Graph and LinearCode in the catalogue. But there will only be few of them anyway, so perhaps one should rather strive for consistency here. Though I know nothing about two-graphs, it therefore seems that I would vote for putting TwoGraph in graphs.tab. Well, a TwoGraph is not a graph but that's another problem :-P Hehe, OK.

I uploaded the new sagetex tarball there. Everything seems to work; my only suggestion is to somehow allow someone to download a file with the original file name, instead of its SHA1. I made an issue on your repo: https://github.com/vbraun/SageDevApp/issues/1. I will try this out with the new eclib tarball for trac #19091 (later today).

[sage-devel] Re: make ssl no longer works
as far as I understand, everything still should be OK for Sage 6.8. (otherwise it's a bloody mess...)

Or is there something they can still download from some Sage-related server? -- You received this message because you are subscribed to the Google Groups sage-devel group.
