What is the generating function for Legendre polynomial?

What is the generating function for Legendre polynomial?

The Legendre polynomials can be alternatively given by the generating function ( 1 − 2 x z + z 2 ) − 1 / 2 = ∑ n = 0 ∞ P n ( x ) z n , but there are other generating functions.

Why are Legendre polynomials useful?

For example, Legendre and Associate Legendre polynomials are widely used in the determination of wave functions of electrons in the orbits of an atom [3], [4] and in the determination of potential functions in the spherically symmetric geometry [5], etc.

What is hermite differential equation?

where is a constant is known as Hermite differential equation. When is an. odd integer i.e., when = 2 + 1; = 0,1,2 … …. then one of the solutions of. equation (1) becomes a polynomial.

How are Legendre polynomials used in expanding functions?

Legendre polynomials are also useful in expanding functions of the form (this is the same as before, written a little differently): which arise naturally in multipole expansions. The left-hand side of the equation is the generating function for the Legendre polynomials.

How to calculate the orthogonality of the Legendre polynomial?

dx(1− x2)n= 2 2n+1 The orthogonality integral is for the associated Legendre polynomials is expressed as; R1 −1 dxPm r(j)Pm k(x) = 2j2+1 (j +m)! (j − m)! The normailzation for the Legendre polynomial Pm ris found for m = 0. 3 Recurrence Relations

Which is the solution to the Associated Legendre differential equation?

The associated Legendre polynomials are solutions to the associated Legendre Differential Equation , where is a Positive Integer and ., . They can be given in terms of the unassociated polynomials by

Where do Legendre polynomials occur in Laplace’s equation?

Legendre polynomials occur in the solution of Laplace’s equation of the static potential, ∇2 Φ(x) = 0, in a charge-free region of space, using the method of separation of variables, where the boundary conditions have axial symmetry (no dependence on an azimuthal angle ).
