Cosine

Compute the cosine of a number.

Usage

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

cos( x )

Computes the cosine of a number (in radians).

var v = cos( 0.0 );
// returns 1.0

v = cos( 3.141592653589793/4.0 );
// returns ~0.707

v = cos( -3.141592653589793/6.0 );
// returns ~0.866

v = cos( NaN );
// returns NaN

Examples

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

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

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