WebThe interval of convergence of a power series is the set of all x-values for which the power series converges. Let us find the interval of convergence of ∞ ∑ n=0 xn n. which means that the power series converges at least on ( −1,1). Now, we need to check its convergence at the endpoints: x = −1 and x = 1. which is convergent.
