Evaluate the following integral on the interval \(\left(-\frac{\pi}2;\frac{\pi}2\right)\).
\[
\int \left ( \frac{3}
{\cos ^{2}x} - 3\mathrm{e}^{x}\right )\, \mathrm{d}x
\]
\(3\mathop{\mathrm{tg}}\nolimits x - 3\mathrm{e}^{x} + c,\ c\in \mathbb{R}\)
\(- 3\mathop{\mathrm{tg}}\nolimits x - 3\mathrm{e}^{x} + c,\ c\in \mathbb{R}\)
\(- 3\mathop{\mathrm{tg}}\nolimits x + 3\mathrm{e}^{x} + c,\ c\in \mathbb{R}\)
\(3\mathop{\mathrm{tg}}\nolimits x + 3\mathrm{e}^{x} + c,\ c\in \mathbb{R}\)
