9-31.

The graph at right represents the height above ground of a rider on The Screamer. Draw a unit circle and mark each of the corresponding locations of the labeled points. Then describe where the rider is located at each point.

Draw a unit circle. Notice that point A is slightly past $90^\circ$. Where is that on the unit circle?

To locate point B, determine how the graph in the problem is scaled.
