Verifying trigonometric identities using even and odd

The video tutorial explains how to simplify a trigonometric expression using identities and reciprocals. It starts with the expression cosecant of negative X divided by secant of negative X and aims to transform it into negative cotangent X. The instructor demonstrates the use of even and odd identities, rearranges the expression, and simplifies it by multiplying with reciprocals. The tutorial concludes with a summary of the method and a preview of the next problem.
