WebIntegral Test. Suppose that f f is a continuous, positive, and decreasing function of x x on the infinite interval [1,∞) [ 1, ∞) and that an = f(n). a n = f ( n). Then ∞ ∑ n=1an and ∫ ∞ 1 f(x)dx ∑ n = 1 ∞ a n and ∫ 1 ∞ f ( x) d x … WebIf the ratio near infinity is less than 1, then we know for certain that each term is becoming less and less and the series will converge. If the ratio near infinity is greater than 1, then we know that each term will continue to grow, so the series will diverge.
WebFor each of the following series, determine which convergence test is the best to use and explain why. Then determine if the series converges or diverges. If the series is an alternating series, determine whether it converges absolutely, converges conditionally, or diverges. ∞ ∑ n = 1 n2 + 2n n3 + 3n2 + 1. ∞ ∑ n = 1 n 2 + 2 n n 3 + 3 n ... WebJan 2, 2024 · When the test shows convergence it does not tell you what the series converges to, merely that it converges. Determine if ∞ ∑ n = 1 n 2n is convergent. …
