Inverse Functions and Definite Integrals

The video tutorial explains how to evaluate a given definite integral by comparing the integrand function to known integration formulas. It demonstrates finding the anti-derivative using the inverse sine function and calculating the definite integral's value. The tutorial also includes a graphical representation of the integrand function and the area under the curve, emphasizing that the integral's value equals this area.
