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.

Discuss the flexibility in choosing methods to solve trigonometric problems as mentioned in the text.
