Double Integrals and Antiderivatives

The video tutorial explains how to evaluate a double integral over a specified region by changing the order of integration for simplicity. It covers setting up the integral with new limits, performing integration with respect to y and x, and using long division to simplify the process. The tutorial concludes with the final evaluation and interpretation of the result, providing both an exact value and a decimal approximation.

What is the integrand function in the given double integral problem?
