[SciPy-user] symbolic math & scipy (& maxima)...

Hi,
I need to find out the (first) derivative of associated Legendre polynomials
defined in lpmn(m,n,x).
The problem is that I want to derive vs theta where x=cos(theta).
For instance, for m=1 & n=0,
P_0^1(cos(theta)) = cos(theta) -> P_0^1'(cos(theta)) = -sin(theta)
I know that scipy has not symbolic math module (and pythonica seems
to be quite old & unmaintained).
But I use maxima.
So I wonder if it would be possible to run maxima, derive
assoc_legendre_p(n,m,cos(theta)) vs. theta and "send" the result to python.
How could I do that ?
Cheers,
