Inverse sine, result in radians



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.

The 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


asin uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see
