Use the generating function to find the first five (5) Legendre polynomials and verify their your answer using Rodrigues's formula.

Solutions

Expert Solution

On equating thevcoefficients of t​​​​​n for n= 0, 1, 2, 3, 4 we find first few Legendre polynomial

By Rodrigues's formula

P​​​​​​0(x) = 1

p​​​​​​1(x) = (1/1! × 21) (d/dx)(x​​​​​​2 - 1) = (1/2)(2x) = x

Similerly putting n = 4 we find P4(x) = (1/8)(35x4 - 30 x​​​​​​2 + 3)

in the book, Legendre polynomials are obtained to the degree 5. Normalize polynomials P4 and P5 so that P4(1) = 1 and p5(1) = 1. This is standard normalization and these will be standard Legendre polynomials. Use the recurrence relation for standard Legendre polynomials to find two more (standard) Legendre polynomials. Show your work for credit. Hint: The recurrence relation: (n+1) P_{n+1}(x) = (2n+1) P_{n}(x) - n P_{n-1}(x)}
