Hey!
I have made the final documentation and code touches to my many variable
separation trees, I have rebased and rewritten the history (only ) and
now I consider it to be tree-ready :)
Please pull from my github's 'variable-separation' branch.
You can pull from git://github.com/plaes/sympy.gi

While trying to figure out the cause of bug #1527, I noticed some
low-hanging stuff that could be easily fixed.. :)
While looking around in sympy/core/function.py I noticed it contains
bunch of extend*() functionality, which IMHO does not belong there.
So I decided to move all these functions to

Previously sympy failed to integrate things like this:

Out[3]:

With patch applied:

Ran into another problem with simplify()..

Hey!
I played a bit with sympy and when trying to solve some quasilinear
differential equations, but had to first make sure that sympy can handle
some simpler forms of PDEs.
The patches can be seen from:
https://code.plaes.org/git/sympy/log/?h=pde-upstream
Cheers,
Priit :)

Cleaned up dsolve, added PDE support for deriv_degree, moved ODE handling
into its own function and add solver stub for PDEs.

I didn't check the math part, but in the jn_zeros() docstring there's
method = "sympy" instead of "scipy" in one place.

Yes, but for some reason it was not applied... :(
But this patch also adds solver for this extra case where bernoulli's
solution cannot be used.
