Find the radius and interval of convergence.∑n=1∞(−1)n(x−4)n(7n)n Ratio Test for Series Convergence: Here the test that can be applied will be dependent on the type of the series. For the alternating series, the ratio test or the divergence test can...
Of course, the series might converge at some values of x and diverge at others. The following definition expresses this more formally. Definition 1.1. The above series converges at x if and only if lim N→∞N n=0 a n (x−x...

Convergence Interval: If you know the interval of convergence, you can derive the radius of convergence from it. The easiest way to get the interval of convergence is to use the Ratio test for series. Answer and Explanation:1 {eq}\; \sum_{n=0}^{\in...

The radius of convergence is the distance from the point about which we are expanding to the closest point at which the function is not analytic, and the interval of convergence extends by this distance in either direction. From: Mathematics for Physical Chemistry (Fourth Edition), 2013 ...
