Inverse Trigonometric Functions and Their Properties

This video tutorial explains how to evaluate inverse trigonometric expressions involving inverse cosecant, secant, and cotangent using the unit circle. It covers the range restrictions for each function and demonstrates how to find angles with specific trigonometric values. The video provides examples for each inverse function, showing how to use the unit circle to determine the correct angle in radians or degrees.
