Learn how to simplify trig identities by adding two terms

The video tutorial focuses on simplifying trigonometric identities. It begins with an introduction to the concept of simplification and explores different forms of trigonometric functions like sine, cosine, and tangent. The instructor then demonstrates a step-by-step process to simplify a given trigonometric expression by transforming tangent and combining fractions with common denominators. Finally, the tutorial applies trigonometric identities, specifically the Pythagorean identity, to achieve a simplified expression.
