QSIN(length, angle, twopi) : y Looking for Background Information
in Propeller 2
QSIN(length, angle, twopi) : y Rotate (length,0) by (angle / twopi) * 2Pi and return y. Use 0 for twopi = $1_0000_0000. Twopi is unsigned.
Curious about the background for how this method is being calculated.

If you want 360 to equal one revolution, set twopi to 360. Then, the remainder of angle / 360 will be the degrees.
