Verifying a trigonometric Identities

The video tutorial explains how to simplify a trigonometric expression using identities. The instructor starts by choosing the more complex side of the equation and applies trigonometric identities, particularly the Pythagorean identity, to simplify the expression. The process involves rewriting sine in terms of cosine and verifying the identity by ensuring both sides of the equation match. The tutorial concludes with a successful verification of the trigonometric identity.
