     37 ## Usage
     38 
     39 ```javascript
     40 var iterSin = require( '@stdlib/math/iter/special/sin' );
     41 ```
     42 
     43 #### iterSin( iterator )
     44 
     45 Returns an [iterator][mdn-iterator-protocol] which iteratively computes the [sine][@stdlib/math/base/special/sin].
     46 
     47 ```javascript
     48 var array2iterator = require( '@stdlib/array/to-iterator' );
     49 
     50 var src = [ 0.0, 3.141592653589793/2.0, -3.141592653589793/6.0 ];
     51 var it = iterSin( array2iterator( src ) );
     52 // returns <Object>
     53 
     54 var r = it.next().value;
     55 // returns ~0.0
     56 
     57 r = it.next().value;
     58 // returns ~1.0
     59 
     60 r = it.next().value;
     61 // returns ~-0.5
     62 
     63 // ...
     64 ```
     65 
     66 The returned [iterator][mdn-iterator-protocol] protocol-compliant object has the following properties:
     67 
     68 -   **next**: function which returns an [iterator][mdn-iterator-protocol] protocol-compliant object containing the next iterated value (if one exists) assigned to a `value` property and a `done` property having a `boolean` value indicating whether the iterator is finished.
     69 -   **return**: function which closes an [iterator][mdn-iterator-protocol] and returns a single (optional) argument in an [iterator][mdn-iterator-protocol] protocol-compliant object.

     79 ## Notes
     80 
     81 -   If an iterated value is non-numeric (including `NaN`), the returned [iterator][mdn-iterator-protocol] returns `NaN`. If non-numeric iterated values are possible, you are advised to provide an [`iterator`][mdn-iterator-protocol] which type checks and handles non-numeric values accordingly.
     82 -   If an environment supports `Symbol.iterator` **and** a provided [iterator][mdn-iterator-protocol] is iterable, the returned [iterator][mdn-iterator-protocol] is iterable.
