Y = asin(X)
returns the inverse sine (arcsine) for each element of
X. For real elements of
X in the domain ,
asin(X) is in the range . For real elements of
x outside the range ,
asin(X) is complex.
asin function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Graph the inverse sine function over the domain .
The inverse sine can be defined as
