By putting the modulus of the ratio less than 1 we can find it. The radius of convergence is the average of the extremities of the interval of convergence. Answer and Explanation: {eq}\lim_{n\rightarrow \infty}\frac{(-6)^{n+1}(x-3)^{n+1}}{\sqrt{n+1...
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...
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...
