Vypočtěte \[ \int \frac{\cos 2x} {\cos ^{2}x}\, \mathrm{d}x \] na intervalu \(\left(0;\frac{\pi}2\right)\).
\(2x -\mathop{\mathrm{tg}}\nolimits x + c,\ c\in \mathbb{R}\)
\(\frac{\sin 2x} {\frac{1} {3} \sin ^{3}x} + c,\ c\in \mathbb{R}\)
\(2x +\mathop{\mathrm{cotg}}\nolimits x + c,\ c\in \mathbb{R}\)
