Instructions
Use the sliders above to change the shape of the Lissajous curve. Investigate how each slider affects the pattern created. Your mission is the find the settings that produce a perfectly symmetrical (vertically and horizontally) infinity symbol.
For those with a knowledge of trigonometry the parametric equations of the curve currently showing at the top of this page are:
