Goal: To use inverse trig functions to help us solve equations.

Recall:

A function is a set of ordered pairs (inputs and outputs) such that no two different ordered pairs have the same first coordinate. A function passes the Vertical Line Test. We usually symbolize y as a function of x by

1.

y = f(x).A function is one-to-one if no two different ordered pairs have the same second coordinate. A one-to-one function passes the Horizontal Line Test.

2.

The inverse of a function f is obtained by switching the first and second coordinates in all the ordered pairs that comprise f. The inverse of f is denoted by f

3.

The domain and range of f and f are flip-flopped.4.
