Power Series | Power Series & Interval of Convergence: Example 3

The video tutorial explains how to determine the interval of convergence for a power series using the ratio test. It begins with an introduction to the series and the concept of interval of convergence. The ratio test is applied to find the limit L, and the limit expression is simplified. The inequality is solved to find the interval of convergence, and the endpoints are checked to determine if the power series converges at those points. The tutorial concludes with a discussion on the radius of convergence.
