Compare the two definite integrals \( I_1=\int\limits_{-1}^1\left(x+\frac{\pi}2\right)\mathrm{d}x \) and \( I_2=\int\limits_0^{\frac{\pi}4}\mathrm{tg}\,x\cdot\cos x\,\mathrm{d}x \).
\( I_1 \) is bigger than \( I_2 \).
\( I_1 \) is smaller than \( I_2 \).
\( I_1 \) is equal to \( I_2 \).
These integrals cannot be compared.
