Main Question or Discussion Point
Hello, I have two questions regarding the Radius of convergence.
1. What should we do at the interval (Reps, R)
2. It used definition to prove radius of convergence, but I am not sure if it is necessarysufficient condition of convergence. I get that this can be a sufficient condition but not sure of the necessity
