Master Evaluate the six trigonometric functions using the unit circle

The video tutorial explains how to evaluate the six trigonometric functions using the unit circle for angles π/2 and 3π. It covers the basic understanding of the unit circle, the coordinates involved, and how to calculate sine, cosine, tangent, and their reciprocal functions. The tutorial emphasizes the importance of understanding the coordinates where the angle intercepts the unit circle and provides examples of undefined values when dividing by zero.
