Množina řešení nerovnice \( \mathrm{cotg}\left(3x -\frac{\pi}4 \right) \geq -1 \) pro \( x\in\left\langle0;\frac{\pi}2\right\rangle \) je:
\( \{0\}\cup\left( \frac{\pi}{12};\frac{\pi}3 \right\rangle\cup\left(\frac{5\pi}{12};\frac{\pi}2\right\rangle \)
\( \left\langle 0;\frac{\pi}3\right\rangle \)
\( \left( \frac{\pi}{12};\frac{\pi}3\right\rangle \)
\( \left( 0;\frac{\pi}2\right\rangle \)
