Najdi množinu všech \( x\in\mathbb{R} \) pro které \( \sin\!\left(\frac{\pi}6 + x\right) = -0{,}5 \).
\( \bigcup\limits_{k\in\mathbb{Z}}\left\{\frac{5\pi}3+2k\pi;\ \pi+2k\pi\right\} \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left\{\frac{\pi}2 + 2k\pi;\ \frac{5\pi}3+2k\pi\right\} \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left\{\frac{5\pi}3+2k\pi\right\} \)
\( \bigcup\limits_{k\in\mathbb{Z}}\left\{\frac{7\pi}6+2k\pi;\ \frac{11\pi}6+2k\pi\right\} \)
