The Twelve Part Unit Circle
Definition

In the illustration below, the x and y-axes partition the unit circle into four equal arcs. The locations of intersection are ( 1, 0 ),

( 0, 1 ), (-1, 0 ) and ( 0, -1).


The Unit Circle

For the twelve part circle, each of the the four arcs can be trisected and the locations determined. Follow the animation below to see how this is done.

Recall that θ can represent either a directed arclength starting from the initial point ( 1, 0 ) or an angle with an initial arm along the positive x-axis. In either case, counterclockwise is positive.
