Q 57 Find the interval of convergence of (x-1)"
(-1,1)
nn
​

Answer 1

Step-by-step explanation:

If the power series only converges for x=a then the radius of convergence is R=0 and the interval of convergence is x=a . Likewise, if the power series converges for every x the radius of convergence is R=∞ and interval of convergence is −∞<x<∞ − ∞ < x < ∞ .May 26, 2020
