Compare two definite integrals \( I_1=\int\limits_0^{\frac{\pi}2}\cos x\,\mathrm{d}x \) and \( I_2=\int\limits_0^{2\pi}2\cos x\,\mathrm{d}x \).
\( I_1 \) is bigger than \( I_2 \) by \( 1 \).
\( I_1 \) is smaller than \( I_2 \) by \( 1 \).
\( I_1 \) is equal to \( I_2 \).
\( I_1 \) is smaller than \( I_2 \) by \( 2 \).
