csc - Cosecant of argument in radians

Syntax

Y = csc(x)

Description

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

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

Examples

Graph the 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)), grid on

Definition

The cosecant can be defined as

Algorithm

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