If the interval of convergence of a series is (-1,1), it means that the series converges for all values of x within the open interval (-1,1), but it diverges for x = -1 and x = 1.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
