Description

Sine function. SIN(x) returns the sine of the angle x. The result range is [-1..1]. The argument x must be expressed in radians. To convert degrees to radians you use the RADIANS function.

The argument x can be a real number, a complex number, or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the SIN function applied to all elements.

Example

SIN(PI()/6) equals 0.5.

SIN(RADIANS(90)) equals 1.
