Trigonometry for animation

Computers have a lot more affinity to radians

1 radian = 57.2958 degrees

6.2832 radians = 360 degrees

π = 3.1416

2π = 6.2832 radians = 360 degrees

360° = 2π

180° = π

90° = π/2

Rotation property of a sprite / movie clip is measured in degrees

Radians for angle

Degrees for rotation

Formula

radians = degrees*Math.PI/180

degrees = radians*180/Math.PI
