* Calculate the hyperbolic arccotangent of a value,

* defined as `acoth(x) = atanh(1/x) = (ln((x+1)/x) + ln(x/(x-1))) / 2`.

|
* For matrices, the function is evaluated element wise.

* Syntax:

|
*
|

|
|
* math.acoth(x)

|
|
* Examples:
|

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