Remarks
The SINfunction takes an angle and returns the ratio of two sides of a right triangle. The result lies in the range -1 to 1. The ratio is the length of the side opposite the angle divided by the length of the hypotenuse. The angle argument can be any valid numeric expression measured in radians.
To convert degrees to radians, multiply degrees by Pi/180. To convert radians to degrees, multiply radians by 180/Pi. Pi is approximately 3.141593.
