Construction of the cos curve


The following animation may help you visualize the construction of the cos graph.

Recall that for a unit circle x = cos q and y = sin q, where q is the angle counterclockwise from the positive x-axis. Thus the horizontal position x of a point on the circle becomes the height of a point on the graph of x = cos q. Thus, to view the graph of x = cos q, you must tilt your head to the right.
