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

• 

acsc

Inverse cosecant

Syntax

• Y = acsc(X)
  

Description

Y = acsc(X) returns the inverse cosecant (arccosecant) for each element of X.

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

Examples

Graph the inverse cosecant over the domains and .

• x1 = -10:0.01:-1.01;
  x2 = 1.01:0.01:10;
  plot(x1,acsc(x1),x2,acsc(x2)), grid on
  
  
  

Definition

The inverse cosecant can be defined as

acsch

Inverse cosecant and inverse hyperbolic cosecant

Syntax

• Y = acsch(X)
  

Description

Y = acsch(X) returns the inverse hyperbolic cosecant for each element of X.

The acsch 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 cosecant over the domains and .

• x1 = -20:0.01:-1;
  x2 = 1:0.01:20;
  plot(x1,acsch(x1),x2,acsch(x2)), grid on
