Here is a set of practice problems to accompany the Power Series section of the Series & Sequences chapter of the notes for Paul Dawkins Calculus II course at Lamar University.The radius of convergence of a power series f centered on a point a is equal to the distance from a to the nearest point where f cannot be defined in a way that makes it holomorphic. The set of all points whose distance to a is strictly less than the radius of convergence is called the disk of convergence .Convergence of a Power Series. Since the terms in a power series involve a variable x, the series may converge for certain values of x and diverge for other values of x. For a power series centered at x = a, x = a, the value of the series at x = a x = a is given by c 0. c 0. Therefore, a power series always converges at its center.7.

The radius of convergence will be R = (c – b) / 2. Two extremes are possible: The radius of convergence can be zero, which will result in an interval of convergence with a single point, a (the interval of convergence is never empty). Or, for power series which is convergent for all x-values, the radius of convergence is +∞.
