**Chapter 2 / Section 2.2 "closed form" Qs**

« **on:**October 12, 2020, 02:35:52 PM »

Questions 14-18 ask us to find a "closed form" for each power series. I assume this is a non-power series expression (e.g. e

^{x}). Some of the power series seem to be variants on the geometric series, but then the closed form would only hold for some z based on the value of |z|, depending on the series. Would it be ok to just specify that the solution only holds for some z?
