Tutorial

## Introduction to Inverse Trigonometric Functions

This video introduces the inverse trigonometric functions and identifies some of their properties. NOTE: there are three inverse trigonometric functions: arcsin, arccos, and arctan. All of them input a value and output the angle at which their corresponding trigonometric function equals that value.
