Thanks for forwarding it. I read the Sage
I know some of you guys are related to SAGE development.
I think it was polite behavior to forward this post I made in SAGE
group to your list as well.
Thank you very much for the great work!

Yeah. I was changing all of my sympy's to SymPy and I must have
accidently changed the link.

Yes, all tests are fine. Thanks for running it!

The differential equation solving engine of sympy is very limited
right now. You can look in the dsolve function in the solvers file in
the source to see what it can solve. It basically can solve linear,
Bernoulli, and some special cases of first and second order
equations. If I get acc
I also meant to say that when one puts sin(t) instead of g(t) in the
dsolve, it still does not work. So, it seems clear that this just has
not been implemented (yet?).

Hi,
I have a need to have sympy solve the following second order
differential equation for f(t) using dsolve:
dsolve(f(t).diff(t,t) + f(t).diff(t) + mu**2 *f(t) - g(t) , f(t))
where mu is a constant and g(t) is at least twice differentiable. The
homogeneous equation is easy enough with dsolve:

My plan is not to use any external software that would introduce extra
dependencies

So
On the other hand, I have tried again on the isympy console,
where .subs() works for (e*f*e*f) but not for (e*e*f);
In [15]: (e*e*f).subs(e*f,f*e+h)
Out[15]:
2
e *f
In [16]: (e*f*e*f).subs(e*f,f*e+h)
Out[16]:
2
(h + f*e)
Is it true that isympy console uses another piece of code?
I ha
Very interesting.
Could you please add more details for how you intend to implement the solvers?
Will you write them from scratch? Wrap known solvers?
I saw no mention of numerical PDE solvers. Are you planning on
only implementing symbolic solvers?
Can you possibly compare to known symbolic so

Hey,
Please take some time to look into my GSOC application:
at http://wiki.sympy.org/wiki/GSoC2009Application/PriitLaes
I am very happy if you can point out typos, bad wording, things that
need a better explanation and of course - please mention things that
sound impossible :)
Cheers,
Priit
