Choose a graph to trace: Sine, Cosine, or both[br]Click on Start Animation to begin or stop the trace.[br]You may also drag the orange point around the circle to manually trace the curves.

Given y = sin(x), each point on the curve is given by (x, sin(x)).[br]Each point on the curve y = cos(x) is given by (x,cos(x)).[br][br]Investigation: Graph both y = sin(x) and y = cos(x) simultaneously. How is the graph of y = sin(x) related to the graph of y = cos(x)?[br][br][br][br]This is a modification of the GeoGebra applet created by Winzeler_BASIS.
