How to evaluate for the composition of the tangent and cosine

The video tutorial explains the restrictions on angles for tangent and sine functions, emphasizing the importance of staying within specified limits. It discusses the cosine of π using the unit circle and explores the concept of tan inverse, focusing on finding angles that produce specific tangent values. The tutorial also covers reflections over the axes to determine the correct angle within given constraints.
