    If memory serves me correctly, you can generate the Legendre polynomials using Gram-Schmidt orthogonalization on the interval [tex] -1 \leq x \leq 1 [/tex] starting with a constant 1 as [tex] L_0 [/tex].

    The generating function method is used to calculate moments of charge distributions.

    You have to master them to get anywhere in physics., they pop up all the time.

    Yup, assuming you start with the linearly independent set [tex]\{ 1, \, x, \, x^2, \, x^3 \ldots \} [/tex].
