The Legendre Polynomial has many applications, including the solution of the hydrogen atom wave functions in single-particle quantum mechanics. It is written as: M (2n-2m)! Pn(x) = E (-1)m, 2"m!(n – m)!(n – 2m)! m=0 n-1 or M= whichever gives an integer. 2 where M= Derive the formula for P,(x) up to n=3 completely. Compute a 7D value of the Legendre polynomial of degree n, Pn(x) for X= 1.2199. With the four (4) reference x values 1.2, 1.3, 1.4, and 1.5, use the Newton's Forward Difference Formula.
