Spirograph (Trochoids)

This interactive simulator explores Spirograph (Trochoids) in Math Visualization. Hypo- or epitrochoid: fixed R, rolling r, pen d; hue trail and period hints. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Suited to beginners and first exposure to the topic. Typical context: Math Visualization.

How it works

Trochoids are the clean cousin of Lissajous: one parameter traces a gear-mounted pen, producing roses, stars, and dense fills.
