Simplifying a trigonometric expression by subtracting rational expressions

The video tutorial explains how to simplify a trigonometric expression involving sine, cosine, tangent, and secant. It begins by rewriting sine over cosine as tangent and using reciprocal identities to express the terms in terms of secant. The tutorial then applies Pythagorean identities to relate tangent and secant, allowing for further simplification. Finally, the distributive property is used to simplify the expression to its simplest form, demonstrating the process of reducing complex trigonometric identities.
