Archavercosine

Compute the inverse half-value versed cosine.

The inverse half-value versed cosine is defined as

Inverse half-value versed cosine.

Usage

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

ahavercos( x )

Computes the inverse half-value versed cosine.

var v = ahavercos( 0.0 );
// returns ~3.1416

v = ahavercos( 1.0 );
// returns 0.0

v = ahavercos( 0.5 );
// returns ~1.5708

If x < 0, x > 1, or x is NaN, the function returns NaN.

var v = ahavercos( 1.5 );
// returns NaN

v = ahavercos( -3.14 );
// returns NaN

v = ahavercos( NaN );
// returns NaN

Examples

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

var x = linspace( 0.0, 1.0, 100 );
var i;

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