Integral dari $$$\frac{2 y^{2}}{3}$$$

Temukan $$$\int \frac{2 y^{2}}{3}\, dy$$$.

Terapkan aturan pengali konstanta $$$\int c f{\left(y \right)}\, dy = c \int f{\left(y \right)}\, dy$$$ dengan $$$c=\frac{2}{3}$$$ dan $$$f{\left(y \right)} = y^{2}$$$:

$${\color{red}{\int{\frac{2 y^{2}}{3} d y}}} = {\color{red}{\left(\frac{2 \int{y^{2} d y}}{3}\right)}}$$

Terapkan aturan pangkat $$$\int y^{n}\, dy = \frac{y^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ dengan $$$n=2$$$:

$$\frac{2 {\color{red}{\int{y^{2} d y}}}}{3}=\frac{2 {\color{red}{\frac{y^{1 + 2}}{1 + 2}}}}{3}=\frac{2 {\color{red}{\left(\frac{y^{3}}{3}\right)}}}{3}$$

Oleh karena itu,

$$\int{\frac{2 y^{2}}{3} d y} = \frac{2 y^{3}}{9}$$

Tambahkan konstanta integrasi:

$$\int{\frac{2 y^{2}}{3} d y} = \frac{2 y^{3}}{9}+C$$

$$$\int \frac{2 y^{2}}{3}\, dy = \frac{2 y^{3}}{9} + C$$$A
