Vedclass · Answer

(A) माना $P = \sin \frac{\pi}{12} \sin \frac{2 \pi}{12} \sin \frac{3 \pi}{12} \sin \frac{4 \pi}{12} \sin \frac{5 \pi}{12} \sin \frac{6 \pi}{12}$.मान रखने पर:$\sin \frac{\pi}{12} = \frac{\sqrt{6}-\sqrt{2}}{4}$,$\sin \frac{2 \pi}{12} = \frac{1}{2}$,$\sin \frac{3 \pi}{12} = \frac{1}{\sqrt{2}}$,$\sin \frac{4 \pi}{12} = \frac{\sqrt{3}}{2}$,$\sin \frac{5 \pi}{12} = \frac{\sqrt{6}+\sqrt{2}}{4}$,$\sin \frac{6 \pi}{12} = 1$.अतः,$P = \left( \frac{6-2}{16} ight) \left( \frac{\sqrt{3}}{4 \sqrt{2}} ight) = \frac{1}{4} 	imes \frac{\sqrt{3}}{4 \sqrt{2}} = \frac{\sqrt{3}}{16 \sqrt{2}}$.
