/**
|
|
* Calculate the hyperbolic cotangent of a value,
|
|
* defined as `coth(x) = 1 / tanh(x)`.
|
|
*
|
|
* To avoid confusion with the matrix hyperbolic cotangent, this function
|
|
* does not apply to matrices.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.coth(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* // coth(x) = 1 / tanh(x)
|
|
* math.coth(2) // returns 1.0373147207275482
|
|
* 1 / math.tanh(2) // returns 1.0373147207275482
