How to determine if a series diverges
WebA. The series does not satisfy the conditions of the Alternating Series Test but diverges by the Root Test because the limit used does not exist. B. The series converges by the; Question: Determine whether the alternating series ∑n=1∞(−1)n+1nlnn converges or diverges. Choose the correct answer below and, if necessary, fill in the answer ... WebNov 16, 2024 · If the power series only converges for x =a x = a then the radius of convergence is R = 0 R = 0 and the interval of convergence is x = a x = a. Likewise, if the power series converges for every x x the radius of convergence is R = ∞ R = ∞ and interval of convergence is −∞ < x <∞ − ∞ < x < ∞. Let’s work one more example.

The comparison tests require … WebDec 29, 2024 · We can show the series ∞ ∑ n = 1 ( − 1)n n + 3 n2 + 2n + 5 = ∞ ∑ n = 1 n + 3 n2 + 2n + 5 diverges using the Limit Comparison Test, comparing with 1 / n. The series ∞ ∑ n = 1( − 1)n n + 3 n2 + 2n + 5 converges using the Alternating Series Test; we conclude it converges conditionally.
WebNov 16, 2024 · The original test statement was for a series that started at a general n =k n = k and while the proof can be done for that it will be easier if we assume that the series starts at n =1 n = 1. Another way of dealing with the n =k n = k is we could do an index shift and start the series at n =1 n = 1 and then do the Integral Test.
