Hacoversine

NPM version Build Status Coverage Status

Compute the half-value coversed sine.

The half-value coversed sine is defined as

Half-value coversed sine.

Installation

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

Usage

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

hacoversin( x )

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

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

v = hacoversin( 3.141592653589793/2.0 );
// returns 0.0

v = hacoversin( -3.141592653589793/6.0 );
// returns 0.75

Examples

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

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

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