The SymPy–Sage interface needs some work in general; many special functions
in SymPy don't have `_sage_` methods, and thus can't be converted back to
Sage. Maybe Sage should use its conversions table like it does for Maxima.

Hi Roland,
Not inappropriate, but the request is better made on the sage-devel mailing
list. I may try to shepherd it personally but I am not the only person that can
do it. I think there may even be a ticket for it.

Actually, more precisely pynac uses:
sin(x).series(x == 3, 5)
to get a taylor expansion about x = 3. I did this
only for consistency with GiNaC, since that is what
GiNaC does.

OK, excellent. Let me know when you do, so I can add support
for them to some key SAGE classes (e.g., rational numbers, univariate
polynomials, etc.)

I think SymPy is going to be useful when a good geometry module is
released, and hopefully a trigonometry module will also come out. Once
that happens it won't take much to meet the needs of all high school
math classes since we already have really good symbolic support that

Just a clarification since I didn't write it clearly: I think the SAGE
environment is great, but getting stuck in any environment is
something

How fast should a symbolic computation library be? What is the fastest
symbolic computation library?

Hi all,
I am the lead developer of SymPy and I just wanted to clarify a few
things about SymPy's motivations.
1) Speed is not a (top) priority. Rewriting it in C++ will maybe be
done in the future, but definitely not now, as we are still playing
with the design. However, I think that rewriting t
If SymPy was written in C++ and had a Python interface in it what
would be the likely hood of it being the backend for symbolic
computation in SAGE?

I have talked with Ondrej Certik many times. He wants a pure Python
library for symbolic computation. Bobby has SymPy in his sage.math
directory. I am very impressed with how well that project is going. I
just think it will actually be useful. Bobby has worked very hard to
make the exact kind of f

I definitely agree that SAGE's goals are quite a bit higher and more
ambitious than those outlined on the SymPy project. While looking over the
SymPy website, I was just surprised because I had never heard of the project
and their scope seemed to be much wider than I had initially thought
