DRAWTRIG.8xp

Summary: Generates the graphs of trigonometric functions. Both the unit circle and the trigonometric function (from 0 to 2π) are graphed simultaneously for comparison. User may select any of the six trigonometric functions. Great for class demonstrations.

No set up is required, simply run the program and follow directions. You can press ENTER to pause at any time during the graphing. I like to do this after each quadrant. The program will leave your calculator in parametric, radian and simultaneous mode. Remember to reset your modes to their previous settings if necessary.
