Returns the sine of the given angle.
Number is the angle in radians for which you want the sine. If your argument is in degrees, multiply it by PI()/180 to convert it to radians.
SIN(PI()) equals 1.22E-16, which is approximately 0 (zero). The sine of p is zero.
SIN(PI()/2) equals 1
SIN(30*PI()/180) equals 0.5, the sine of 30 degrees
