Package Exports

@stdlib/math-base-special-hacovercos

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-hacovercos) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Hacovercosine

$NPM version$ $Build Status$ $Coverage Status$ $dependencies$

Compute the half-value coversed cosine.

The half-value coversed cosine is defined as

$Half-value coversed cosine.$

Installation

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

Usage

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

hacovercos( x )

Computes the half-value coversed cosine (in radians).

var v = hacovercos( 0.0 );
// returns 0.5

v = hacovercos( 3.141592653589793/2.0 );
// returns 1.0

v = hacovercos( -3.141592653589793/6.0 );
// returns 0.25

Examples

var linspace = require( '@stdlib/array-linspace' );
var TWO_PI = require( '@stdlib/constants-float64-two-pi' );
var hacovercos = require( '@stdlib/math-base-special-hacovercos' );

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

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