Evaluate the following indefinite integral on \( \left(-\frac{\pi}2;\frac{\pi}2 \right) \). \[ \int \left(\frac1{\cos x}-\sin x\cdot\mathrm{tg}\,x\right)\,\mathrm{d}x \]
\( \sin x+c\text{, }c\in\mathbb{R} \)
\( \cos x+c\text{, }c\in\mathbb{R} \)
\( -\sin x+c\text{, }c\in\mathbb{R} \)
\( -\cos x+c\text{, }c\in\mathbb{R} \)
