Problem

$\sin\bigl(\tfrac{\pi}{3}\bigr)$

Step-by-step solution

$\frac{\pi}{3}$ radianos $= 60°$ .
No círculo unitário em $60°$ , a coordenada y é $\frac{\sqrt{3}}{2}$ .
O seno é igual à coordenada y: $\sin\bigl(\tfrac{\pi}{3}\bigr) = \frac{\sqrt{3}}{2}$ .

Answer

$\sin\bigl(\tfrac{\pi}{3}\bigr) = \tfrac{\sqrt{3}}{2}$
