The familiar trigonometric functions can be geometrically derived from a circle.
But what if, instead of the circle, we used a regular polygon?
In this animation, we see what the “polygonal sine” looks like for the square and the hexagon. The polygon is such that the inscribed circle has radius 1. (There’s a very neat reason for this.)
Since these polygons are not perfectly symmetrical like the circle, the function will depend on the orientation of the polygon.

Check out this beefy Ducati. Pretty nice, I’ll take one in black!
