Evaluate the integral of an expression given an integrand

The video tutorial begins with an introduction and setup of a mathematical problem. The teacher explains the problem and initial steps, discussing the representation of functions and distribution. The solution approach is discussed, including integration, but the teacher suggests a more efficient method using rectangles. The evaluation is completed using the rectangle method, calculating the base and area to find the solution.
