Inverse trigonometric functions we know from their graphs that none of the trigonometric functions are onetoone over their entire domains. A function is called onetoone if no two values of \x\ produce the same \y\. So that would be f inverse, or were saying g is the same thing as f inverse. In other words, there are two different values of x that produce the same value of y. However, we can restrict those functions to subsets of their domains where they are onetoone. If you rotate the graph in the figure counterclockwise so that the line y x is vertical, you can easily see that these functions are mirror images of each other.
