Inverse sine in radians


y = asin(x)


y = asin(x) returns the Inverse Sine (sin-1) of the elements of x. The asin function operates element-wise on arrays. For real elements of x in the interval [-1,1], asin(x) returns values in the interval [-pi/2,pi/2]. For real elements of x outside the interval [-1,1] and for complex values of x, asin(x) returns complex values. All angles are in radians.

Find the inverse sine of the elements of vector x. The asin function acts on x element-wise.

x = [0.5i 1+3i -2.2+i];
y = asin(x)
y =

   0.0000 + 0.4812i   0.3076 + 1.8642i  -1.1091 + 1.5480i

Graph the inverse sine over the domain $-1 \le x \le 1$.
