WebA review of all series tests. Consider the series ∑ n ∞ a n. Divergence Test: If lim n → ∞ a n ≠ 0, then ∑ n a n diverges. Integral Test: If a n = f ( n), where f ( x) is a non-negative non-increasing function, then. ∑ n ∞ a n converges if and only if the integral ∫ 1 ∞ f ( x) d x converges. Comparison Test: This applies ... WebMar 7, 2024 · Here we show how to use the convergence or divergence of these series to prove convergence or divergence for other series, using a method called the comparison test. For example, consider the series. ∞ ∑ n = 1 1 n2 + 1. This series looks similar to the convergent series. ∞ ∑ n = 1 1 n2. byroy.com
