ACOTH function
Inverse hyperbolic cotangent function. ACOTH(x) returns the inverse hyperbolic cotangent of x. x must satisfy |x| > 1 (i.e. x < −1 or x > 1).
The inverse hyperbolic cotangent can be expressed as a natural logarithm:
$$ \operatorname{acoth}(x) = \frac{1}{2}\ln\!\left(\frac{x+1}{x-1}\right) $$
The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the ACOTH function applied to all elements.
Examples
ACOTH(2) equals 0.5493061
ACOTH(−2) equals −0.5493061
