Modified Associated Legendre Polynomial Nodes

[Vortexman]

Hello,

I am currently using modified Associated Legendre polynomials to solve differential equations. Essentially, I am expanding functions as A = \Sigma A_{n} \sin (\theta) P_{n}^{1} ( \cos (\theta) ) . My question is whether or not I should be using the standard Gauss-Legendre nodes, or should I be using different grid points?

Thanks,

Vortexman
