GeoGebra Graphics 2 and the Sine and Cosine Functions

Move the point on the circle in the left window (Graphics 1).

This is a Java Applet created using GeoGebra from - it looks like you don't have Java installed, please go to

This applet demonstrates how to use Graphics 2 of GeoGebra. Graphics 1 shows the distances on the circle: distance traveled (a)  by a point about the circle from (1,0), it's distance from the x-axis (b), and its distance from the y-axis (c).

Graphics 2 shows the two points with coordinates (a,b) and (a,c). The traces of the points in Graphics 2 forms the graph of the sine function and the consine function from 0 to pi.
