Simplifying Trigonometric Expressions

The video tutorial explains how to simplify trigonometric expressions by converting them into sines and cosines. It provides two examples: one involving the multiplication of cosecant theta and tangent theta, and another involving the division of secant theta by tangent theta. The tutorial emphasizes the importance of recognizing common factors and converting division problems into multiplication problems to simplify expressions effectively.
