How does domain restrictions affect the inverse of trig composition

The video tutorial explains the composition of inverse functions, focusing on cosine. It begins with evaluating the cosine of π/4 and its inverse, highlighting the importance of domain restrictions. The instructor then provides an example using cosine of 5π/4, demonstrating reflections about the axes. The tutorial concludes by discussing negative cosine values and their domain restrictions, emphasizing the need to understand these concepts for accurate evaluations.
