acsc, acsch (MATLAB Function Reference)

Inverse cosecant and inverse hyperbolic cosecant

Y = acsc(X)
Y = acsch(X)

The acsc and acsch functions operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are in radians.

Y = acsc(X)

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

Y = acsch(X)

returns the inverse hyperbolic cosecant for each element of X.

Examples

Graph the inverse cosecant over the domains

and

and the inverse hyperbolic cosecant over the domains

and

x1 = -10:0.01:-1.01; x2 = 1.01:0.01:10;
plot(x1,acsc(x1),x2,acsc(x2))
x1 = -20:0.01:-1; x2 = 1:0.01:20; 
plot(x1,acsch(x1),x2,acsch(x2))
