Question: Define P n (x) by Use the reduction formula in Exercise 64 to prove that P n (x) = x n nP n1 (x).

Define Pn(x) by

[xe dx = P xe* dx= Pn(x) et + C

Use the reduction formula in Exercise 64 to prove that Pn(x) = xn − nPn−1(x). Use this recursion relation to find Pn(x) for n = 1, 2, 3, 4. P0(x) = 1.


Data From Exercise 64

Derive the reduction formula [xedx= xe-n fx=dx

[xe dx = P xe* dx= Pn(x) et + C
