Find the point with radius and angle

Question

I\'m not a genius in geometry, I\'d like to find a point in as3 with the radius and a angle but I don\'t remember the rule, I know thi

Answer 1

as3.x = centerX + radius * cos(angle)
as3.y = centerY + radius * sin(angle)

Note that the rotation in the picture linked to is in the "negative direction". I.e, an increase of the angle, yields a counter-clockwise rotation.
