Evaluating Definite Integrals and Antiderivatives

The video tutorial explains how to evaluate a definite integral by simplifying the integrand function, finding the antiderivative, and applying the limits of integration. It also includes a graphical interpretation of the integrand function over a specified interval, highlighting the area under the curve.
