Sin Function

Returns the sine of an angle. The angle is specified in radians. The result lies between -1 and 1.

Using the angle Alpha, the Sin Function returns the ratio of the length of the opposite side of an angle to the length of the hypotenuse in a right-angled triangle.

Sin(Alpha) = side opposite the angle/hypotenuse
