## Lesson 8-3: Inverse Trig Functions

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

## Objective:

The student will be able to evaluate the general and principal solutions of inverse trig functions.

1. In the graph, the red curve is a portion of y = sin(x), trace over the curve, thinking of the ordered pairs that make up this graph.
2. The blue curve is the inverse of y = sin(x), trace over the curve, see that each ordered pair is the reverse of a corresponding point on the y = sin(x) curve.
3. What line of symmetry lies between the two curves?
4. See the "Hands-On Activities" section for Inverse Sine, Cosine and Tangent applets.
