Riešením nerovnice \( \cos^2x\leq0{,}25 \) pre \( x\in\langle0;2\pi\rangle \) je množina:
\( \left\langle \frac{\pi}3;\frac{2\pi}3\right\rangle\cup\left\langle \frac{4\pi}3;\frac{5\pi}3\right\rangle \)
\( \left\langle \frac{\pi}3;\frac{5\pi}3\right\rangle \)
\( \left\langle 0;\frac{2\pi}3\right\rangle \)
\( \left\langle 0;\frac{5\pi}3\right\rangle \)
