The Integral Test for Convergence. Suppose that is a continuous, positive, decreasing function on the interval and let . Then the series defined by is convergent if and only if the improper integral is convergent. In other words, If is convergent, then is convergent. or. If is divergent, then is divergent. p-series Test for Convergence

The Integral Test. For a function f, if f (x) > 0, is continuous and decreasing for and , then. either both converge or both diverge. Note: The integral test is only a test for convergence or divergence. In the case of convergence, it does not find a value for the sum of the series. Example 1: Determine the convergence or divergence of the series

Since we are looking for an antiderivative of and we know that we can re-write our integral as . In practice, we use the following substitution scheme to verify that we can integrate in this way: 4. Integrate with respect to : where and . 3. Change the original integral in to an integral in : 2. Differentiate both sides so . 1. Let . 5.

Determine using integral test whether the series convergent or divergent. a) is a p – series with p = 4 > 1, which is convergent. Now we will verify using integral test. converges, thus the series converges. b) is a p – series with p = 0.85 < 1, which is divergent. Now we will verify using integral test. does not exist.
