Hello,
I would like to know that for example (log(x) + 1)-((log(x)**3+7) is a
polynom of log(x). How can I do ?
Best regards.
Christophe.

Use cse() (common subexpression elimination). It will replace the
logs with dummy variables, which you can then see is a polynomial.
In [8]: cse((log(x) + 1)-((log(x)**3+7)))
Out[8]: ([(x0, log(x))], [-6 + x0 - x0**3])
I think you can then tell that this is a Polynomial by trying to
instanti
Indeed I know how to test is an expression is a ploynom regarding to one
variable.
The use of ces() will solve my problem.
Thanks a lot.
Christophe.

We are releasing another release candidate before the final 0.6.5
release, since we found some bugs in the last release candidate and
wanted to make sure we did not break anything. Please test this so we
can make a final release this week.
Changes since last stable release

Any thoughts on this?

The SciPy conference committee is pleased to announce the schedule of the
conference:

This year’s program is very rich. In order to limit the number of
interesting talks that we had to turn down, we decided to reduce the
length of talks. Although this results
Hmmm. I may have pushed the wrong branch. That patch doesn't look
right.

Hi,
SymPy was accepted both for the tutorial and a 40 min talk at the
SciPy 2009 conference:
http://conference.scipy.org/schedule
http://conference.scipy.org/abstract?id=3
I'll give the tutorial using sympy that is in all distributions/Sage,
e.g. 0.6.4, or even older, like 0.6.2 in EPD. However

I am still on IRC, feel free to come, we'll fix it.

Sounds great. Please post the slides (or if it is recorded, post

talk about how SymPy started, and I am interested in learning about
that.

Hi! My student, William Flynn, has been working a lot this summer using
sympy--thanks for all of the efforts on this project. We're doing some
work in a windows environment and find that pretty printing (to generate
pngs) still has a problem. Our hack at the moment is to use the python

I just wanted to check--will the patches for noncommutative numbers be
included in this release?
Thanks,

Thanks for using it and trying to fix the noncommutative problems and
other things.

Wow, you guys are quick! We'll check on this tomorrow.
