Topic: Trigonometric Identities
Subtopic: Identities Involving Inverse Trig Functions


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/√2))) and simplifying algebraically via circle diagrams and trigonometric identities.


By the end of this topic you should know and be prepared to be tested on:
