* Simultaneously computes the sine and cosine of a number.

* @returns {(Array|TypedArray|Object)} sine and cosine
*
* @example
* var v = sincos( 0.0 );
* // returns [ ~0.0, ~1.0 ]
*
* @example
* var v = sincos( 3.141592653589793/2.0 );

*
* @example
* var v = sincos( -3.141592653589793/6.0 );
* // returns [ ~-0.5, ~0.866 ]
*
* @example
* var v = sincos( NaN );
* // returns [ NaN, NaN ]
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var out = new Float64Array( 2 );
*
* var v = sincos( out, 0.0 );
* // return <Float64Array>[ ~0.0, ~1.0 ]
