Graphs of Inverse Functions

Inverse Sine Function The horizontal line test shows that the sine function is not one-to-one and has no inverse function.

The Restricted Domain

Graph the Inverse Sine xy -.707 0.707 1 xy 0.707 1

Graph of Inverse Sine xy 0.707 1

Inverse Cosine Function As with the sine, the domain must again be restricted. For cosine we restrict to

Graph the Inverse Cosine xy 01.707 0 -.707 xy 10.707 0 -.707

Graph of Inverse Cosine xy 10.707 0 -.707

Inverse Tangent Function

Graph the Inverse Tangent xy und 0 1 und xy 0 1

Graph of Inverse Tangent xy und 0 1
