Artist's Description

The parametric equation for one of the shapes associated with spirographs along with an example.

The variable “a” is the radius of the first circle that the second one “b” revolves around (think planets).

The “b” value is the radius of the circle on the outside that turns on the edge of the middle circle.

The variable T is kind of like the step. As the graph moves, the T controls how far the values are placed apart (i.e. you could have a straight line, skipping all the points in between, or you could plot the whole curve).

The variable “p” is the pen offset. When it is equal to “b”, the pen starts at the edge of the smaller circle.
