3-179.

Let *f*(*x*) = *y*.

Solve for *x*.

Switch the *x* and *y*.

Do not forget the ±. What will the graph of the inverse look like? Will there be exactly one output for each input?

To determine if the inverse is a function: Visualize! What does a cube root graph look like?

If *f*(*x*) = sin(*x*)

Then *f* ^{−1}(*x*) = arcsin(*x*) = sin^{−1}(*x*)

Note: csc*x* is the reciprocal of sin*x*, not the inverse!
