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.

Examples

Graph the inverse hyperbolic cotangent over the domains and .

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

Definition

The hyperbolic inverse cotangent can be defined as

Algorithm

acoth uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see http://www.netlib.org.
