Intro

Intro to the integral test for series convergence

Ex.1

Ex.2

Ex.3

Testing a series with cube root of ln in the denominator for divergence

Applying the integral test to the series 3 over n squared

Proving the harmonic series diverges using the integral test

Testing convergence of a series with a fifth root using the integral test

Applying the integral test with partial fractions to prove convergence

In this section, we will learn about another test called the Integral test. The idea is to take the general term as a function in terms of x, and then integrate it. You can only use this test if the function is positively decreasing. If the integral gives a finite value, then the series is convergent. If the integral diverges to infinity, then the series is also divergent. We will first do some questions that require you to use the integral test instead of p-series test. Then we will use the integral test on a complicated series to see if it converges or diverges.
