Ferris Wheel Trigonometry

This is an updated version of my ferris wheel applet... Now with dual screen. :)[br][br]This is a demonstration of a ferris wheel I created in GeoGebra designed to inspire and motivate my students to learn about trigonometric transformations. Dr. Gail Kaplan's lesson plan, Trigonometry Through a Ferris Wheel, inspired me to create this applet. http://www.nctm.org/publications/arti... [br][br]When the "run ferris wheel" button is pressed, the ferris wheel will complete two cycles. The red point will generate an x and y coordinate about 6 times a second, where x is time and y is height. All of these points together should form a wave function. Can you figure out what that wave function is?[br][br]Thanks to @mathhombre for inspiring me to make this applet dual screen, and thank you GeoGebra community for answering all my questions that helped me to develop this applet...
