I created a program located at http://www.ptrone.com/
Where changing the value of z to
cos(point)*120+120
Creates a circle that is rotating in a circular motion.
Can anyone tell the formula to create a triangle that rotates in a circular motion?

What I have tried:

cos(), sin(), exp() ...
How do I use the formulas
