Compute the inverse coversed sine.

The inverse coversed sine is defined as

Inverse coversed sine.

Installation

npm install @stdlib/math-base-special-acoversin

Usage

var acoversin = require( '@stdlib/math-base-special-acoversin' );

acoversin( x )

Computes the inverse coversed sine.

var v = acoversin( 0.0 );
// returns ~1.5708

v = acoversin( 3.141592653589793/2.0 );
// returns ~-0.6075

v = acoversin( 3.141592653589793/6.0 );
// returns ~0.4966

If x < 0, x > 2, or x is NaN, the function returns NaN.

var v = acoversin( -1.0 );
// returns NaN

v = acoversin( 3.14 );
// returns NaN

v = acoversin( NaN );
// returns NaN

Examples

var linspace = require( '@stdlib/array-linspace' );
var acoversin = require( '@stdlib/math-base-special-acoversin' );

var x = linspace( 0.0, 2.0, 100 );
var i;

for ( i = 0; i < x.length; i++ ) {
    console.log( acoversin( x[ i ] ) );
}
