Integral dari $$$\frac{1}{13 y}$$$

Temukan $$$\int \frac{1}{13 y}\, dy$$$.

Terapkan aturan pengali konstanta $$$\int c f{\left(y \right)}\, dy = c \int f{\left(y \right)}\, dy$$$ dengan $$$c=\frac{1}{13}$$$ dan $$$f{\left(y \right)} = \frac{1}{y}$$$:

$${\color{red}{\int{\frac{1}{13 y} d y}}} = {\color{red}{\left(\frac{\int{\frac{1}{y} d y}}{13}\right)}}$$

Integral dari $$$\frac{1}{y}$$$ adalah $$$\int{\frac{1}{y} d y} = \ln{\left(\left|{y}\right| \right)}$$$:

$$\frac{{\color{red}{\int{\frac{1}{y} d y}}}}{13} = \frac{{\color{red}{\ln{\left(\left|{y}\right| \right)}}}}{13}$$

Oleh karena itu,

$$\int{\frac{1}{13 y} d y} = \frac{\ln{\left(\left|{y}\right| \right)}}{13}$$

Tambahkan konstanta integrasi:

$$\int{\frac{1}{13 y} d y} = \frac{\ln{\left(\left|{y}\right| \right)}}{13}+C$$

$$$\int \frac{1}{13 y}\, dy = \frac{\ln\left(\left|{y}\right|\right)}{13} + C$$$A
