Computes the sinesine of a number.

Installation

$ npm install math-sin

Usage

var sin = require( 'math-sin' );

sin( x )

Computes the sinesine of a number (in radians).

var val = sin( 0 );
// returns ~0

val = sin( Math.PI/2 );
// returns ~1

val = sin( -Math.PI/6 );
// returns ~-1/2

Examples

var linspace = require( 'compute-linspace' );
var sin = require( 'math-sin' );

var x = linspace( 0, 2*Math.PI, 100 );
var i;

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