asin

Inverse sine

Syntax

• Y = asin(X)
  

Description

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.

Examples

Graph the inverse sine function over the domain .

• x = -1:.01:1; 
  plot(x,asin(x)), grid on
  

Definition

The inverse sine can be defined as

Algorithm

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