Although convergence of ∫ ∞ N f(x)dx implies convergence of the related series ∞ ∑ n = 1an, it does not imply that the value of the integral and the series are the same. They may be different, and often are. For example, ∞ ∑ n = 1(1 e)n = 1 e + (1 e)2 + (1 e)3 + ⋯.

Webb27 aug. 2014 · Well, I would try to see if I can directly compare first; however, it might not be easy when its expression is complicated. The benefit of the limit comparison test is that we can compare series without verifying the inequality we need in order to apply the direct comparison test, of course, at the cost of having to evaluate the limit. WebbIf so, try the comparison test or limit comparison test. Do the terms in the series contain a factorial or power? If the terms are powers such that a n = b n n, a n = b n n, try the root test first. Otherwise, try the ratio test first. Use the divergence test. If this test does not provide any information, try the integral test. how to spot fake rolex watches https://growbizmarketing.com
