### Power Series 1b - Interval of Convergence Using Ratio Test

For a given power series function, we show how to find the interval of convergence using the ratio test. Particular care must be applied to the endpoints. Examples used are (a) sum n! x^n, (b) sum (x-1)^n/n!, and (c) sum (x+2)^n/n. For more videos like this one, please visit the Calculus playlists at this channel.
