Riešenie trigonometrickej rovnice substitúciou
Rieš v \( \mathbb{R} \) rovnici pomocou substitúcie:
\( \sin \left(x-\frac{2 \pi}{3}\right)= \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{7 \pi}{4}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{5 \pi}{6}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{7 \pi}{6}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{11 \pi}{6}+2 k \pi\right\} \)
