Explore the graph of the function

considered as a circular function.

Using Trig3:

- Press to start the drawing of the graph.
- Press any key to suspend the drawing; then the pressing of any key will resume the drawing. There is no way to stop the drawing and start over from the beginning without killing the program.
- After the graph has been drawn, you can press
- to clear the graph,
- to redraw the graph but you should press first,
- to decrease the delay in the drawing of the graph,
- to make the drawing of the graph slower, and
- to quit the program.
