Course: Trigonometry
Topic: Trigonometric Identities
Subtopic: Identities Involving Inverse Trig Functions

Overview

Our goal in this lesson is to meld inverse trigonometric functions and trigonometric identities. Here we simplify expressions that contain inverse trig functions and in some way involve a trig identity too. This topic involves taking quite complicated expressions (such as `cos(arcsin(0.6) - arctan(-2))` and `sin(2 cos^-1(x/sqrt2))`) and simplifying algebraically via circle diagrams and trigonometric identities.
