Nettet11. apr. 2024 · The integral test is simply a method that helps to determine the convergence or divergence of an infinite series by comparing it to the integral of a related function. In simple terms, the integral test states that “if the function f (x) is continuous, positive, and decreasing on the interval [n, ∞) and if the series a n is also positive ... NettetExample Consider the infinite series Determine whether it is convergent using the integral test. Complete Solution Step 1: Pull Out the Negative Sign where If S converges, then the given infinite series converges. Step 2: Check to see if the integral test can be applied Let . Then f ( x) is continuous f ( x) is decreasing f ( x) is non-negative
