Master How to evaluate using the cofunction identities

The video tutorial provides an introduction to cofunction identities in trigonometry, explaining their significance and how they relate to the unit circle. It covers the relationships between sine and cosine, tangent and cotangent, and cosecant and secant, demonstrating how these identities can simplify calculations and problem-solving in tests or without a unit circle. The tutorial emphasizes the importance of recognizing these identities for efficient problem-solving.
