Integral Aljabar: Bentuk Dasar

Bentuk Dasar

$\int x^{n} d x = \frac{1}{n + 1} . x^{n + 1} + c$

$\int x^{- 1} d x = \ln | x | + c$

$\int k d x = k x + c$ , k adalah konstanta

Contoh 01

$\begin{aligned} \int x^{4} d x & = \frac{1}{4 + 1} . x^{4 + 1} + c \\ \int x^{4} d x & = \frac{1}{5} x^{5} + c \end{aligned}$

Contoh 02

$\begin{aligned} \int 3 x^{8} d x & = 3 . \frac{1}{8 + 1} . x^{8 + 1} + c \\ \int 3 x^{8} d x & = \frac{1}{3} x^{9} + c \end{aligned}$

Contoh 03

$\begin{aligned} \int \sqrt{x} d x & = \int x^{\frac{1}{2}} d x \\ \int \sqrt{x} d x & = \frac{1}{\frac{1}{2} + 1} . x^{\frac{1}{2} + 1} + c \\ \int \sqrt{x} d x & = \frac{1}{\frac{3}{2}} . x^{\frac{1}{2} + 1} + c \\ \int \sqrt{x} d x & = \frac{2}{3} x^{1 \frac{1}{2}} + c \\ \int \sqrt{x} d x & = \frac{2}{3} x \sqrt{x} + c \end{aligned}$

Contoh 04

$\begin{aligned} \int \frac{1}{x^{3}} d x & = \int x^{- 3} d x \\ \int \frac{1}{x^{3}} d x & = \frac{1}{- 3 + 1} . x^{- 3 + 1} + c \\ \int \frac{1}{x^{3}} d x & = - \frac{1}{2} x^{- 2} + c \\ \int \frac{1}{x^{3}} d x & = - \frac{1}{2 x^{2}} + c \end{aligned}$

Contoh 05

$\begin{aligned} \int \frac{2}{x} d x & = 2 \int \frac{1}{x} d x \\ \int \frac{2}{x} d x & = 2 \ln | x | + c \end{aligned}$

Contoh 06

$\begin{aligned} \int 4 d x & = 4 x + c \end{aligned}$
