Ratio Test: The ratio test is a test for determining whether a series converges. A power series is any series of the following form: Notice how the power series differs from the geometric series: In a geometric series, every term has the same coefficient. The function associated with is differentiable in the disc of convergence, and the function represented by agrees with on the disc of convergence. As we will see, the values of x for which a power series converges is always an interval. Then and have the same radius of convergence. Getting worse usually means the series goes to infinity for some values of x. Within its interval of convergence, the derivative of a power series is the sum of derivatives of individual terms: [Σf(x)]'=Σf'(x).
