Explore inverse trigonometric functions and their compositions in this comprehensive 36-minute video lesson. Begin by revisiting one-to-one functions and the squaring function, then learn how to restrict domains and find inverses of trigonometric functions. Examine graphs of sine, cosine, and tangent functions along with their inverse counterparts. Practice solving problems involving inverse sine, cosine, tangent, cotangent, secant, and cosecant values. Conclude with a summary table of inverse trigonometric functions and work through examples to find exact values using these concepts.
