Definition
Legendre's associated differential equation is a second order ODE of the form:
- $\ds \paren {1 - x^2} \frac {\d^2 y} {\d x^2} - 2 x \frac {\d y} {\d x} + \paren {n \paren {n + 1} - \frac {m^2} {1 - x^2} } y = 0$
where $m$ and $n$ are complex numbers.
Solutions of this equation are called associated Legendre functions.
