Description
An interactive simulation of a physical Scotch yoke mechanism that visualizes how trigonometric functions are derived from a point rotating around a wheel. Users can manipulate the wheel's radius and speed, toggle projections, and switch between time-based and arc-length-based paper rolls to see how the waves are generated.
