Introduction to Topic 11.4 - Inverse Trigonometric Functions

We have practiced a lot of problems evaluating the six trigonometric functions for a given angle. What if you have the reverse problem – you have a value of a trigonometric function and you need to find the corresponding angle?

In this topic, we will learn how to use the inverse trigonometric functions for this particular type of problem.

Essential question: How do we find the measure of an angle given the value of a trigonometric function?
