Series | The Integral Test: Example #2

The video tutorial covers the integral test for series, demonstrating how to determine if a series converges or diverges. It begins with a recap of the theory and a previous example where the integral diverged. The tutorial then sets up a new series, proving it is positive and decreasing. The integral test is applied using a u substitution, and the integral is evaluated to show convergence. The conclusion emphasizes that the integral test indicates convergence but does not provide the series' value.
