TR3.1 - The Inverse Functions of Sine and Cosine
Channel: MATH 1151
Date: 11/03/2019

The Inverse Functions of Sine and Cosine introduces the inverses to the basic trig functions. These functions y = sin−1 (x) and y = cos−1 (x) are also denoted y = arcsin(x) and y = arccos(x) respectively, as is mentioned in Right Triangle Geometry. It relies on the unit circle values found in The Unit Circle - Part I and Part II. It is helpful to have an understanding of how the graph of a function illustrates the domain and range of a function, and further details of the domain and range of the inverse trig functions are given in Domain and Range of Trig and Inverse Trig Functions.
