The solution set of the equation \( \mathrm{tg}\,x + \mathrm{cotg}\,x = 2 \) for \( x\in[-2\pi;2\pi] \) is:
\( \left\{-\frac{7\pi}4;-\frac{3\pi}4;\frac{\pi}4;\frac{5\pi}4 \right\} \)
\( \left\{-\frac{7\pi}4;\frac{\pi}4;\right\} \)
\( \left\{-\frac{5\pi}4;-\frac{\pi}4;\frac{3\pi}4;\frac{7\pi}4 \right\} \)
\( \left\{-\frac{3\pi}4;\frac{\pi}4\right\} \)
