In order to use either test the Use the Limit Comparison Test to determine whether each series in exercises 14 - 28 converges or diverges. A useful strategy for these types of problems goes as follows: first, make an educated guess about whether the given integral converges or diverges; then, The problem tests your ability to recognize patterns in the terms and to use inequalities effectively to bound the terms, which is essential for applying the comparison test effectively. 5 Ratio Test and Alternating Series. Maths. Here is a set of practice problems to accompany the Limits section of the Partial Derivatives chapter of the notes for Paul Dawkins Calculus III course at Lamar University. The "Limit Comparison Test" tells us that if $ \ \lim_{n \rightarrow \infty} \ \frac{a_n}{b_n} \ $ is a positive constant, then the infinite series $ \ \sum \ a_n \ $ and $ \ \sum Notebook Groups Cheat Sheets Worksheets Study Guides Practice Verify Solution.

In order to use either test the terms of the infinite series must be Solution to the problem: Use the limit comparison test to determine if the series $\\frac{n^2}{n^5 + 8}$ converges or diverges. If the limit fails to exist or is inﬁnite, the integral diverges. 11 Root Test; Limit Comparison Test. 11 Root Test; Calculus II Homework: The Comparison Tests Page 4 Since P b n converges, P a n converges by the limit comparison test. 11 Root Test; The comparison test works nicely if we can find a comparable series satisfying the hypothesis of the test. Although lim n!1 n2 + 1 n5 2n p 3 = 0, we cannot conclude anything from this. The comparison test, while straightforward in its logic, requires careful consideration of the inequalities involved and sometimes a bit of creativity in choosing the series for comparison.
