Use the generating function to find the first five (5) Legendre polynomials and verify their your answer using Rodrigues's formula.
On equating thevcoefficients of tn for n= 0, 1, 2, 3, 4 we find first few Legendre polynomial
By Rodrigues's formula
P0(x) = 1
p1(x) = (1/1! × 21) (d/dx)(x2 - 1) = (1/2)(2x) = x
Similerly putting n = 4 we find P4(x) = (1/8)(35x4 - 30 x2 + 3)
