|
* Calculate the inverse hyperbolic tangent of a value,

* defined as `acoth(x) = atanh(1/x) = (ln((x+1)/x) + ln(x/(x-1))) / 2`.
|
|
*
|
|
* To avoid confusion with the matrix inverse hyperbolic tangent, this

|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.acoth(x)
|
|

|
|
* Examples:
|
|
*
|
|
* math.acoth(0.5) // returns 0.8047189562170503
