Epic Circle Trace

Profile picture of Nick Halsey

Nick Halsey



A line passes intersects a circle at two points. Each point is located proportionally around the circle in terms of a given function of t. The path of the line’s movement is traced as t varies. Try changing/animating t. Can you figure out how each point is constrained, in terms of t? Look at the gx source file for the answer.

Hint: look at the period of the movement, and how it changes as t changes.
