/**
* Calculate the cotangent of a value. Defined as `cot(x) = 1 / tan(x)`.
*
* To avoid confusion with the matrix cotangent, this function does not
* apply to matrices.
*
* Syntax:
*
* math.cot(x)
*
* Examples:
*
* math.cot(2) // returns number -0.45765755436028577
* 1 / math.tan(2) // returns number -0.45765755436028577
*
* See also:
*
* tan, sec, csc
*
* @param {number | Complex | Unit | Array | Matrix} x Function input
* @return {number | Complex | Array | Matrix} Cotangent of x
