Question

How do I appropriately answer number 13? This is a question from my Differential Equations course, and the name of the chapter is, "Review of Power Series." I think that to determine the radius of convergence is by doing some kind of root test, ratio test, etc.

In each of Proble ms 7 through 13, determine the Taylor series about
the point xo for the given function. Also determine the radius of
convergence of the series.
