Inverse cosecant in radians




Y = acsc(X) returns the Inverse Cosecant (csc-1) of the elements of X. The acsc function operates element-wise on arrays. For real elements of X in intervals [-Inf,-1] and [1,Inf], acsc returns real values in the interval [-pi/2,pi/2]. For real values of X in the interval [-1,1] and for complex values of X, acsc returns complex values. All angles are in radians.

Inverse Cosecant of a Vector of Complex Angles

Find the inverse cosecant of the elements of vector x. The acsc function acts on x element-wise.

x = [0.5i 1+3i -2.2+i];
Y = acsc(x)
Y =

   0.0000 - 1.4436i   0.0959 - 0.2970i  -0.3795 - 0.1833i

Plot the Inverse Cosecant Function

Plot the inverse cosecant function over the intervals $-10\le x <-1$ and $1 < x \le 10$.

x1 = -10:0.01:-1.01;
x2 = 1.01:0.01:10;
