Value of $\sin \frac{\pi}{6} \sin \frac{2 \pi}{6} \sin \frac{4 \pi}{6} \sin \frac{5 \pi}{6}$ is (a) $\frac{3}{8}$ (b) $\frac{3}{16}$ (c) $\frac{\sqrt{3}}{8}$ (d) $\frac{3}{4}$
$\sin ^{4} \frac{\pi}{16}+\sin ^{4} \frac{3 \pi}{16}+\sin ^{4} \frac{5 \pi}{16}+\sin ^{4} \frac{7 \pi}{16}$ equals (a) $2.5$ (b) $1.5$ (c) $2 \sqrt{2}$ (d) $2 \sqrt{3}$
The value of $\sin \frac{\pi}{14} \cdot \sin \frac{3 \pi}{14} \cdot \sin \frac{5 \pi}{14}$ is equal to (a) $\frac{1}{8}$ (b) $-\frac{1}{8}$ (c) $\frac{1}{16}$ (d) $-\frac{1}{16}$
