function sincosd( x, out, stride, offset ) {
	out[ offset ] = sind( x );
	out[ offset + stride ] = cosd( x );
	return out;
}
Simultaneously computes the sine and cosine of an angle measured in degrees and assigns the results to a provided output array.

@private
@param {number} x - input value (in degrees)
@param {Collection} out - output array
@param {integer} stride - output array stride
@param {NonNegativeInteger} offset - output array index offset
@returns {Collection} output array

@example
var v = sincosd( 0.0, [ 0.0, 0.0 ], 1, 0 );
// returns [ ~0.0, ~1.0 ]

@example
var v = sincosd( 90.0, [ 0.0, 0.0 ], 1, 0 );
// returns [ ~1.0, ~0.0 ]

@example
var v = sincosd( -30.0, [ 0.0, 0.0 ], 1, 0 );
// returns [ ~-0.5, ~0.866 ]

@example
var v = sincosd( NaN, [ 0.0, 0.0 ], 1, 0 );
// returns [ NaN, NaN ]
