Rotation Axis Rotation Direction Rotation Angle
For 2d, going to rotate around the z axis, counterclockwise, B degrees.
Want p' (x',y',z'). p (x,y) = (r cos a, r sin a), where r is the distance from origin to p a is the rotation angle from the x-axis
p' = (r cos a+B, r sin a+B) x' = x cos B - y sin B y' = x sin B + y cos B z' = z
