1 мая 2018 г. · The alternating series test. This says that a series converges if (not only if!) the terms go to 0, alternate sign, and have decreasing absolute value. Confused about using alternating test, ratio test, and root test ... Why we ONLY use ratio test and not conditional convergence ... Другие результаты с сайта math.stackexchange.com

29 дек. 2022 г. · If it gives an r < 1 , the absolute value of the terms goes to zero, and therefore in this case it would converge by the alternating series test ...

7 окт. 2007 г. · You can use the alternating series test to see if it converges. If it does, then try applying the Ratio Test ie take the absolute value of the series.

Since L = 1, the ratio test is inconclusive. We can say that the series diverges by the divergence test, lim n→∞ an = lim n→∞ n + 1. 2n - 3. = 1. 2. 6= 0.

28 мар. 2017 г. · No. A series is either convergent or divergent. If it converges it is either absolutely convergent or conditionally convergent. The test used is irrelevant.

20 дек. 2020 г. · The ratio test is particularly useful for series whose terms contain factorials or exponential, where the ratio of terms simplifies the expression.

If your terms contain factorials, or factorials and nth powers, the Ratio Test might be helpful. This test does not care if your terms are negative, and may ...
