Hyperbolic cosecant

csch

Hyperbolic cosecant

Syntax

• Y = csch(x)
  

Description

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

Y = csch(x) returns the hyperbolic cosecant for each element of x.

Examples

Graph the hyperbolic cosecant over the domains and .

• x1 = -pi+0.01:0.01:-0.01;
  x2 = 0.01:0.01:pi-0.01;
  plot(x1,csch(x1),x2,csch(x2)), grid on
  
  
  

Definition

The hyperbolic cosecant can be defined as
