Hi,
I implemented coordinate transformations with sympy, patches are here,
please review:

or download from my git repo, branch curvi:

I implemented it as an example, here is how t

I went ahead and introduced myself there.
I copied what I have above and added some notes to myself on the wiki

Hi Ondrej,
I burrowed into the source code and the problem seems to be caused by
the pattern matching
in the `sympy/core/power.py` file. It expects a term of the form
k*x**l, but if there
are two terms of the same power in x it won't match. This gives l=0
and the
following while loop doesn't term
Another thought:
Make a new diff function and call it pdiff. The only difference
between diff and pdiff would be that pdiff always returns \partial for
'd'.
Not certain that this suggestion is much different than the
above...developers will know, I'm sure.

Most of the time I am dealing with PDEs and as such think it would be
cool if sympy can do the right thing when pprinting an expression
involving partial derivatives. Currently it's my understanding that
only the 'd' gets rendered rather than \partial. So my question is
whether sympy can be educa
