> Computes the [sine][sine] of a number.
`` bash`
$ npm install math-sin
` javascript`
var sin = require( 'math-sin' );
#### sin( x )
Computes the [sine][sine] of a number (in radians).
` javascript
var val = sin( 0 );
// returns ~0
val = sin( Math.PI/2 );
// returns ~1
val = sin( -Math.PI/6 );
// returns ~-1/2
`
` javascript
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 ] ) );
}

This repository uses [tape][tape] for unit tests. To run the tests, execute the following command in the top-level application directory:
` bash`
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
This repository uses [Istanbul][istanbul] as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:
` bash`
$ make test-cov
Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,
` bash`
$ make view-cov
This repository uses [Testling][testling] for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:
` bash`
$ make test-browsers
To view the tests in a local web browser,
` bash``
$ make view-browser-tests
