Theorem (Direct comparison test) If functions f,g : [a,∞) → R are continuous and 0 6 f(x) 6 g(x) for every x ∈ [a,∞), then holds 0 6 Z ∞ a f(x)dx 6 Z ∞ a g(x)dx. The inequalities above imply the following ...We will choose for comparison the p-series ∑ n=1∞ 1/n 2 which is convergent since p = 2 and 2 > 1. 0 ≤ sin 2 n ≤ 1 for all n ∈ Ν , and n 2 + 5 > n 2 for all n ∈ N. So, since each term in the given series is smaller than the corresponding term in the p-series, the series converges. Upvote • 0 Downvote. Add comment.Use this calculator to check the convergence of series using the comparison test. Enter the series and get step-by-step solutions, examples, and explanations.In mathematics, the comparison test, sometimes called the direct comparison test to distinguish it from similar related tests (especially the limit comparison test), provides a way of deducing the convergence or divergence of an infinite series or an improper integral.In both cases, the test works by comparing the given series or integral to one whose …so the new series converges. Like the integral test, the comparison test can be used to show both convergence and divergence. In the case of the integral test, a single calculation will confirm whichever is the case. To use the comparison test we must first have a good idea as to convergence or divergence and pick the sequence for comparison ...Thanks to all of you who support me on Patreon.

Calculus: Early Transcendentals. 8th Edition. ISBN: 9781285741550. Author: James Stewart.Mar 26, 2016 · The direct comparison test is a simple, common-sense rule: If you’ve got a series that’s smaller than a convergent benchmark series, then your series must also converge. And if your series is larger than a divergent benchmark series, then your series must also diverge. Here's the mumbo jumbo. Piece o’ cake. This series resembles. so the new series converges. Like the integral test, the comparison test can be used to show both convergence and divergence. In the case of the integral test, a single calculation will confirm whichever is the case. To use the comparison test we must first have a good idea as to convergence or divergence and pick the sequence for comparison ...It might be helpful to think of the limit comparison test as the test we can use when the direct comparison test doesn’t quite work out. The example in Video 5 is a good candidate for the limit comparison test. The limit comparison test is more sensitive than the direct comparison test and it applies in more examples. Intuition If the limit of ] is infinite, and the sum of ] diverges, then the sum of ] also diverges. Here we are comparing how fast the terms grow. If the limit is positive, then the terms are growing at the same rate, so both series converge or diverge together. If the limit is zero, then the bottom terms are growing more quickly than the top terms.Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
