acoth

Inverse hyperbolic cotangent

Syntax

Y = acoth(X)

Description

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

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

Graph of Inverse Hyperbolic Cotangent Function

Graph the inverse hyperbolic cotangent function over the domains $-30 \le x < -1$ and $1 < x \le 30$.

x1 = -30:0.1:-1.1;
x2 = 1.1:0.1:30;
plot(x1,acoth(x1),x2,acoth(x2)), grid on
