The video tutorial explains how to simplify a trigonometric problem using identities. It starts by setting up the problem and identifying which side to work on. The instructor then applies trigonometric identities, focusing on cotangent and secant, and uses the Pythagorean identity to rewrite expressions. Finally, the tutorial demonstrates how to verify the identity by showing that cotangent and tangent are reciprocals, using the quotient identity to confirm the result.
