<h1 id="function-acoth">Function acoth <a href="#function-acoth" title="Permalink">#</a></h1>
|
|
|
|
Calculate the hyperbolic arccotangent 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 hyperbolic arccotangent, this
|
|
function does not apply to matrices.
