asin - Inverse sine; result in radians

Syntax

Description

Y = asin(X) returns the inverse sine (arcsine) for each element of X. The asin function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians. For real elements of X in the domain [-1,1], asin(X) is in the range

For real elements of x outside the range [-1,1], asin(X) is complex.

Definitions

The arcsine is defined as:

Examples

Graph the inverse sine function over the domain –1 ≤ x ≤ 1.

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