Pre-Calculus - Simplify expressions using fundamental identities, cosβ . tanβ

The video tutorial explains how to use reciprocal and quotient identities to transform and simplify trigonometric expressions. The instructor demonstrates rewriting the tangent of beta as sine over cosine and simplifies the expression by canceling terms. The process results in a simplified expression of sine of beta. The tutorial concludes with a brief summary and closing remarks.
