Verifying an identity by applying the even and odd identities

The video tutorial explains how to verify a trigonometric identity involving tangent, sine, and secant functions. It begins by introducing the problem and then applies even and odd identities to simplify the expression. The instructor breaks down the tangent function and uses trigonometric properties to simplify the expression further. Finally, the identity is verified by showing that the simplified expression equals the given identity.
