Trigo

I need to clarify something.

Am I right to say that when using trigo methods in Flash. Math.atan, atan2, cos, acos blah blah blah, the angles are calculated in counter-clockwise direction starting from 0 radians in the 1st quadrant (the quadrant in the upper-right corner)?

As for _rotation, it’s in degrees in the clockwise direction?

Thanks :eye:
