Riešenie trigonometrickej rovnice so substitúciou
Rieš v \( \mathbb{R} \) rovnici pomocou substitúcie:
\( \sin \left(x+\frac{\pi}{4}\right)=-1 \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{5 \pi}{4}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{3 \pi}{4}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{\pi}{4}+2 k \pi\right\} \)
\( K=\bigcup_{k \in \mathbb{Z}}\left\{\frac{7 \pi}{4}+2 k \pi\right\} \)
