/**
|
|
* Calculate the sine of a value.
|
|
*
|
|
* To avoid confusion with the matrix sine, this function does not apply
|
|
* to matrices.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.sin(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.sin(2) // returns number 0.9092974268256813
|
|
* math.sin(math.pi / 4) // returns number 0.7071067811865475
|
|
* math.sin(math.unit(90, 'deg')) // returns number 1
|
|
* math.sin(math.unit(30, 'deg')) // returns number 0.5
|
|
*
|
|
* const angle = 0.2
|
|
* math.pow(math.sin(angle), 2) + math.pow(math.cos(angle), 2) // returns number ~1
|
|
*
|
|
* See also:
|
|
*
|
|
* cos, tan
|
|
*
|
|
* @param {number | BigNumber | Complex | Unit} x Function input
|
|
* @return {number | BigNumber | Complex} Sine of x
