MATLAB Function Reference

asin, asinh

Inverse sine and inverse hyperbolic sine

Syntax

Y = asin(X)
Y = asinh(X)

Description

The asin and asinh functions operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are 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.

Y = asinh(X) returns the inverse hyperbolic sine for each element of X.

Examples

Graph the inverse sine function over the domain and the inverse hyperbolic sine function over the domain

x = -1:.01:1; plot(x,asin(x))
x = -5:.01:5; plot(x,asinh(x))
