Question

$fraction numerator sin space x over denominator sin space x divided by 8 end fraction equals$

$8 \cos \frac{x}{8} \cos \frac{x}{4} \cos \frac{x}{2}$
$8 \cos \frac{x}{8} \sin \frac{x}{4} \sin \frac{x}{2}$
$8 \sin \frac{x}{8} \sin \frac{x}{4} \sin \frac{x}{2}$
$8 \sin \frac{x}{8} \sin \frac{x}{4} \cos \frac{x}{2}$

The correct answer is: $8 cos space x over 8 cos space x over 4 cos space x over 2$
