Using series you know from Chapter 1, write the power series (about the origin) of the following functions. Use Theorem III to find the disk of convergence of each series. What you are looking for is the point (anywhere in the complex plane) nearest the origin, at which the function does not have a derivative. Then the disk of convergence has center at the origin and extends to that point. The series converges inside the disk. cos z

I think this series diverges, but I’m not sure on my answer nor how to prove it. I’ve tried finding whether the absolute value of the series converges, but I’m also stuck on how to find the convergence/divergence of that. I’m not sure which test to use.
