Výpočet sinu
Vypočti \sin\:\left(\frac{5 \pi}{12}-\frac{\pi}{6}\right).
\sin\:\left(\frac{5 \pi}{12}-\frac{\pi}{6}\right)=\sin\:\frac{\pi}{2}=\sin\:90^{\circ}=1
\sin\:\left(\frac{5 \pi}{12}-\frac{\pi}{6}\right)=\sin\:\frac{\pi}{3}=\sin\:60^{\circ}=\frac{\sqrt{3}}{2}
\sin\:\left(\frac{5 \pi}{12}-\frac{\pi}{6}\right)=\sin\:\frac{\pi}{6}=\sin\:30^{\circ}=\frac{1}{2}
\sin\:\left(\frac{5 \pi}{12}-\frac{\pi}{6}\right)=\sin\:\frac{\pi}{4}=\sin\:45^{\circ}=\frac{\sqrt{2}}{2}
