The video tutorial demonstrates how to verify a trigonometric identity involving secant and cosine. It begins by selecting the more complex side of the equation and rewriting cosine in terms of secant. The tutorial then simplifies the expression by eliminating fractions and multiplying by secant. Finally, it shows that the simplified expression equals the original secant, thus verifying the identity.
