Trigonometric tutorial simplify a trig expression

The video tutorial explores two methods for transforming trigonometric expressions: using secant squared and the Pythagorean identity, or transforming 1 minus sine squared. The instructor chooses the latter for simplicity, demonstrating how to use trigonometric identities to simplify expressions. By rewriting expressions, the tutorial shows how to achieve a simplified result where terms cancel out, ultimately equating to 1. The video emphasizes understanding and applying trigonometric identities for effective simplification.
