Question

Find the associated radius of convergence for..

Answer 1

\[\Large f(x)=(1-x)^{-2}\]

Answer 2

power series expansion

Answer 3

I got it into a series:
\[\Large \sum_{n=0}^{\infty}~(n+1)x^n\]

Answer 4

ok good

Answer 5

So first we find the interval of convergence and divide by 2 for the radius of convergence
