Simplifying Trigonometric Expressions

The video tutorial explains how to simplify trigonometric expressions by converting them into sines and cosines. It demonstrates this process through three examples: simplifying secant x divided by cosecant x to tangent x, tangent x divided by secant x to sine x, and cosecant x divided by cotangent x to secant x. The tutorial uses reciprocal identities and highlights the importance of recognizing common factors to simplify expressions effectively.
