\(\displaystyle \int_a^b f(x) \: dx = F(b) - F(a) \)

Contoh

\begin{equation*} \begin{split} & \int_1^2 (3x^2 - 2x + 5) \: dx \\\\ & \left[x^3 - x^2 + 5x \right]_1^2 \\\\ & \left(2^3 - 2^2 + 5 \:.\: 2 \right) - \left(1^3 - 1^2 + 5 \:.\: 1 \right) \\\\ & \bbox[5px, border: 2px solid magenta] {9} \end{split} \end{equation*}
