Verifying a trigonometric Identities

The video tutorial explains how to verify a trigonometric identity by simplifying one side of the equation to match the other. The instructor chooses the more complex side to simplify, using trigonometric identities and rational expressions. The process involves eliminating fractions, applying Pythagorean identities, and converting expressions to achieve equivalence. The tutorial concludes with a successful verification of the identity, demonstrating the step-by-step approach to solving such problems.
