Now that we have some understanding of inverse functions, let’s recall that sine and cosine functions’ amplitudes never exceeded 1. This probably means there are a similar domain and range cut off for their inverse functions! This is part of the Prelim Maths Extension 1 Syllabus from the topic Trigonometric Functions: Inverse Trigonometric Functions. In this post, we will explore domain and range of inverse functions.
Let’s learn more about trig inverse functions and their domain and range here!
