/**
* Calculate the hyperbolic cosecant of a value,
* defined as `csch(x) = 1 / sinh(x)`.
*
* To avoid confusion with the matrix hyperbolic cosecant, this function
* does not apply to matrices.
*
* Syntax:
*
* math.csch(x)
*
* Examples:
*
* // csch(x) = 1/ sinh(x)
* math.csch(0.5) // returns 1.9190347513349437
* 1 / math.sinh(0.5) // returns 1.9190347513349437
*
* See also:
*
* sinh, sech, coth
*
* @param {number | BigNumber | Complex} x Function input
* @return {number | BigNumber | Complex} Hyperbolic cosecant of x
