The video tutorial explains how to evaluate a definite integral from zero to pi/3 of the function -5 tan^2(theta) - 5 d(theta). It involves changing the form of the integrand using the Pythagorean identity to simplify the expression to -5 sec^2(theta). The antiderivative of sec^2(theta) is known, allowing the calculation of the definite integral. The tutorial concludes with the evaluation of the integral, resulting in -5√3.
