csc, csch (MATLAB Function Reference)

Cosecant and hyperbolic cosecant

Y = csc(x)
Y = csch(x)

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

Y = csc(x)

returns the cosecant for each element of x.

Y = csch(x)

returns the hyperbolic cosecant for each element of x.

Examples

Graph the cosecant and hyperbolic cosecant over the domains

and

x1 = -pi+0.01:0.01:-0.01; x2 = 0.01:0.01:pi-0.01;
plot(x1,csc(x1),x2,csc(x2))
plot(x1,csch(x1),x2,csch(x2))
