Learn how to evaluate for the secant of a negative angle using the unit circle

The video tutorial explains how to understand and visualize angles and reference angles using the unit circle. It covers the concept of reflecting angles about the axes and calculating the secant of an angle. The tutorial emphasizes the importance of understanding these concepts without always relying on the unit circle.

Describe the relationship between the angles and their reflections in the unit circle.

What is the final answer when rationalizing the denominator for the secant calculation?
