Goniometrická rovnica
Nájdi v ℝ riešenie goniometrické rovnice:
\( \normalsize\frac{2}{{\sqrt3}}cotg\left({\frac{x}{2}-\frac{\pi}{4}}\right)=\frac{{2\sqrt3}}{3} \)
\( {x} = {\pi} + 4k \pi \)
\( \normalsize K=\bigcup\limits_{k\in\mathbb{Z}}\left\{\pi+4k\pi\right\} \)
\( {x} = {\pi} + 2k \pi \)
\( \normalsize K=\bigcup\limits_{k\in\mathbb{Z}}\left\{\pi+2k\pi\right\} \)
\( {x} = {\pi} + 3k \pi \)
\( \normalsize K=\bigcup\limits_{k\in\mathbb{Z}}\left\{\pi+3k\pi\right\} \)
\( {x} = {\pi} + k \pi \)
\( \normalsize K=\bigcup\limits_{k\in\mathbb{Z}}\left\{\pi+k\pi\right\} \)
