Phương trình sin x = căn bậc hai 3 / 2 có nghiệm là

$x = \pm \frac{\pi }{3} + k2\pi ,k \in \mathbb{Z}$.

$x = \frac{\pi }{3} + k\pi ,k \in \mathbb{Z}$.

$\left[ \begin{gathered}

x = \frac{\pi }{6} + k\pi \hfill \\

x = \frac{{5\pi }}{6} + k\pi \hfill \\

\end{gathered} \right.,k \in \mathbb{Z}$.

$\left[ \begin{gathered}

x = \frac{\pi }{3} + k2\pi \hfill \\

x = \frac{{2\pi }}{3} + k2\pi \hfill \\

\end{gathered} \right.,k \in \mathbb{Z}$.
