SIN()
Syntax. SIN(number)
Definition. This function returns the sine of a number.
Argument
number (required) The angle in radians for which you want the sine
Background. In a right triangle, the ratio between the hypotenuse and the opposite leg depends on the apex angle. The ratio between the opposite leg of an angle and the hypotenuse is the sine (sin) of an angle.
The SIN() function requires radians for calculations. If the angle is specified in degrees, you have to multiply the angle by PI()/180 or convert it with the RADIANS() function.
The sine of angle α in an unit circle (c = 1) increases up to 90° and has the value 1 in this angle (see Figure 16-27 ...
