El conjunto de soluciones de la inecuación \( \mathrm{cotg}\left(3x -\frac{\pi}4 \right) \geq -1 \) para \( x\in\left[0;\frac{\pi}2\right] \) es:
\( \{0\}\cup\left( \frac{\pi}{12};\frac{\pi}3 \right]\cup\left(\frac{5\pi}{12};\frac{\pi}2\right] \)
\( \left[ 0;\frac{\pi}3\right] \)
\( \left( \frac{\pi}{12};\frac{\pi}3\right] \)
\( \left( 0;\frac{\pi}2\right] \)
