These are already implemented. See legendre, chebyshevt, chebyshevu,
jacob

Maybe this is a different issue, but it seems like it would be good to keep
the representation as a known orthogonal polynomial (which ar

I can't imagine how I missed it, sorry!
Is it possible to have something like chebyshevt(2,x)**2 return
chebyshevt(4,x)/2+chebyshevt(0,x)/

horner is not used, unless you call it yourself.
What we need to do is implement chebyshev and so on in lambdify, so that
they are con

Hi,
I plan to do much more work on orthogonal polynomials
but it will take some (longer) time. First I need to
extend the symbolic summat

Greg, if you want to take a shot at implementing some of these things
yourself, go for it.

Hi,
Right. I did this for spherical harmonics. In principle we need to
cut out all code in the "eval" method and put a clean up version

I would be happy to contribute in any way I can, although my Python
development acumen is pretty weak compared to anyone else here.

The _poly versions do not support symbolic degree. They just explicitly
create the polynomial.
Ideally, the non-poly versions would n

Try to make f.e. the Hermite polynomial non-autoevaluating for
any (numeric as well as symbolic) n and x.
I described what you need to d

Ok. I have started work on this. The current eval in the default case is
getting a pass instead of the poly eval. I will add a new metho
