Syntax

Y = acoth(X)

Description

Y = acoth(X)returns the inverse hyperbolic cotangent for each element ofX.

Theacothfunction operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Inverse Hyperbolic Cotangent

For real values x in the domain − ∞ < x < − 1 and 1 < x < ∞ , the inverse hyperbolic cotangent satisfies

coth − 1 ( x ) = tanh − 1 ( 1 x ) = 1 2 log ( x + 1 x − 1 ) .

For complex numbers z = x + i y as well as real values in the domain − 1 ≤ z ≤ 1 , the callacoth(z)returns complex results.
