acsc - Inverse cosecant; result in radians

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

Algorithm

acsc 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.
