/**
* Calculate the cosecant of a value, defined as `csc(x) = 1/sin(x)`.
*
* To avoid confusion with the matrix cosecant, this function does not
* apply to matrices.
*
* Syntax:
*
* math.csc(x)
*
* Examples:
*
* math.csc(2) // returns number 1.099750170294617
* 1 / math.sin(2) // returns number 1.099750170294617
*
* See also:
*
* sin, sec, cot
*
* @param {number | BigNumber | Complex | Unit} x Function input
* @return {number | BigNumber | Complex} Cosecant of x
