Position around a circle
I’m trying to write an expression that would set the position relative to the angle around the circumference of a circle.
For example (100px circle in middle of comp):
if angle == 0 or 360
[50,0]
if angle == 90
[100,50]
if angle == 180
[50,100]
if angle == 270
[0,50]This only works for the 90 degree increments, so I’m needing a more elegant/mathematic way of doing this that would work for any angle/degree. Any ideas?

Maybe like this:
angle = effect("Angle Control")("Angle");
r = 50; // radius
c = [50,50]; // center
a = degreesToRadians(angle); // angle in radians
c + [Math.sin(a),-Math.cos(a)]*r

Perfect! This is exactly what I needed.
