Think of sympy as a tool not a mathematician ;-) *You* know they are
equal, but sympy doesn't go through contortions to figure out if two
things are equal or not when they don't have the same structure. Your

I've thought that having something showing a flow diagram of how
various operations change things might be useful...more visual
e.g.
type expr.as_coeff_terms().as_numer_denom()
Atom
Rational
Integer
Real
NumberSymbol
Symbol
Add
Mul x/y (1, (x, 1/y)) (x, y)

basically irreducibility can be tested via factorization and usually you
need

Hello all,
I have an issue with an integral I'm trying to evaluate. I have a
matrix where each element is a function of (among other terms) an
integrated Legendre polynomial. My opportunity is that certain
returns are in the form of absolute values. For example, an output to
one particular eleme
Just initiate r as
r = Symbol('r', positive=True).

Wow! My head is lowered in shame. I have no clue why I didn't think of
that. Thank you very much.
Very embarrassed,

What about the algorithms listed at
http://wiki.sympy.org/wiki/GSoC2010Ideas#Detailed_Ideas? Are they still valid,
or have some of these
been implemented already? Are there other good ones not listed? Also, I am
not sure what the prerequisites would be for implementing some of these.

Thanks. I made the bold ones bold because they were mentioned on this thread
as being wanted. Of course, if you disagree or feel others should be bold,
fell free to edit the wiki.
What about the integration and summation algorithms? I can't find much
information about the Karr algorithm, for
Thanks Chris and Mateusz. I reopened issue 1472
http://code.google.com/p/sympy/issues/detail?id=1472
with a patch to substitute the one-liner and add a test.

But it does not checks out the new files in

If you already have a git repository for sympy, just do
git remote add mattpap git://github.com/mattpap/sympy-polys.git
Then do
git fetch mattpap
git checkout mattpap/polys5
git checkout -b polys5
Then you can just to git pull on that branch to update it, and repeat the above
3 for new branc
Thank you a lot. It worked
