WebTo prove the test for divergence, we will show that if ∑ n=1∞ an ∑ n = 1 ∞ a n converges, then the limit, lim n→∞an lim n → ∞ a n, must equal zero. The logic is then that if this limit is not zero, the associated series cannot converge, and it therefore must diverge. We begin by considering the partial sums of the series, SN S N. WebSep 7, 2024 · Figure 9.3.2: The sum of the areas of the rectangles is less than the sum of the area of the first rectangle and the area between the curve f(x) = 1 / x2 and the x -axis for x ≥ 1. Since the area bounded by the curve is finite, the sum of the areas of the rectangles is also finite. Now consider the series ∞ ∑ n = 1 1 n2. at cerdanyola https://kirklandbiosciences.com
