Bentuk Dasar
\(\int x^n \: dx = \dfrac {1}{n + 1} \:.\: x^{n + 1} + c\)
\(\int x^{-1} \: dx = \ln |x| + c\)
\(\int k \: dx = kx + c\), k adalah konstanta
Contoh 01
\begin{equation*} \begin{split} \int x^4 \: dx & = \frac {1}{4 + 1} \:.\: x^{4 + 1} + c \\\\ \int x^4 \: dx & = \frac {1}{5} x^{5} + c \end{split} \end{equation*}
Contoh 02
\begin{equation*} \begin{split} \int 3x^8 \: dx & = 3 \:.\: \frac {1}{8 + 1} \:.\: x^{8 + 1} + c \\\\ \int 3x^8 \: dx & = \frac {1}{3} x^{9} + c \end{split} \end{equation*}
Contoh 03
\begin{equation*} \begin{split} \int \sqrt{x} \: dx & = \int x^{\frac 12} \: dx \\\\ \int \sqrt{x} \: dx & = \frac {1}{\frac 12 + 1} \:.\: x^{\frac 12 + 1} + c \\\\ \int \sqrt{x} \: dx & = \frac {1}{\frac 32} \:.\: x^{\frac 12 + 1} + c \\\\ \int \sqrt{x} \: dx & = \frac {2}{3} x^{1 \frac 12} + c \\\\ \int \sqrt{x} \: dx & = \frac {2}{3} x \sqrt{x} + c \end{split} \end{equation*}
