Legendre addition theorem
NettetGenerating Function for the Legendre Polynomials Just what is says: a way of generating the Legendre functions explicitly, without directly solving the differential equation. Start with the fact that G(~x;~x0) = 1 j~x ~x0j (19) solves the laplace equation, the angular part of which (ignoring ˚) is Legendre’s equation. For r0 NettetThe differential equation for the associated Legendre polynomials, given in eq. (6), depends on m2 and is therefore not sensitive to the sign of m. Consequently, Pm ℓ (x) and P−m ℓ (x) must be equivalent solutions and hence proportional to each other. Using eq. (7), it is straightforward to prove that P− m ℓ (cosθ) = (−1)m (ℓ− ...

Nettet26. mar. 2024 · The addition formula for Legendre polynomials $ P _ {n} ( x ) $ ( P.S. Laplace, 1872) is the prototype of an addition theorem of a more general nature. It gives the explicit Fourier-cosine expansion of $ P _ {n} ( \cos \phi \cos \psi + \sin \phi \sin \psi \cos \theta ) $ in terms of $ \cos m \theta $.
