Find the interval of convergence of this power series by first
using the ratio test to find its radius of convergence and then
testing the series' behavior at the endpoints of the interval
specified by the radius of convergence.
interval of convergence =
(Enter your answer as an interval: thus, if the interval of
convergence were -3 < x < 5, you would enter (-3,5]. Use
Inf for any endpoint at infinity.)
