We investigate the convergence of the binomial series By Exercise 94, T a (x) converges for |x|

Question:

We investigate the convergence of the binomial series

Ta(x) = M8  n=0

By Exercise 94, Ta(x) converges for |x| a(x) = (1 + x)a.

(a) Verify the identity a a(a) = n(a) + (n +  )(  + 1) 1) n+1 (b) Use (a) to show that y = Ta(x) satisfies


Data From Exercise 94

We investigate the convergence of the binomial series

Ta(x) = M8  n=0

Prove that Ta(x) has radius of convergence R = 1 if a is not a whole number. What is the radius of convergence if a is a whole number?
