asin
Compute the arcsine of a number.
Usage
var asin = require( '@stdlib/math/base/special/asin' );
asin( x )
Computes the arcsine of a number
(in radians).
var v = asin( 0.0 );
// returns 0.0
v = asin( -3.141592653589793/6.0 );
// returns ~-0.551
The domain of x
is restricted to [-1,1]
. If |x| > 1
, the function returns NaN
.
var v = asin( -3.14 );
// returns NaN
Examples
var linspace = require( '@stdlib/array/base/linspace' );
var asin = require( '@stdlib/math/base/special/asin' );
var x = linspace( -1.0, 1.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( asin( x[ i ] ) );
}
