Integral de $$$\frac{6}{u}$$$

Encontre $$$\int \frac{6}{u}\, du$$$.

Aplique a regra do múltiplo constante $$$\int c f{\left(u \right)}\, du = c \int f{\left(u \right)}\, du$$$ usando $$$c=6$$$ e $$$f{\left(u \right)} = \frac{1}{u}$$$:

$${\color{red}{\int{\frac{6}{u} d u}}} = {\color{red}{\left(6 \int{\frac{1}{u} d u}\right)}}$$

A integral de $$$\frac{1}{u}$$$ é $$$\int{\frac{1}{u} d u} = \ln{\left(\left|{u}\right| \right)}$$$:

$$6 {\color{red}{\int{\frac{1}{u} d u}}} = 6 {\color{red}{\ln{\left(\left|{u}\right| \right)}}}$$

Portanto,

$$\int{\frac{6}{u} d u} = 6 \ln{\left(\left|{u}\right| \right)}$$

Adicione a constante de integração:

$$\int{\frac{6}{u} d u} = 6 \ln{\left(\left|{u}\right| \right)}+C$$

$$$\int \frac{6}{u}\, du = 6 \ln\left(\left|{u}\right|\right) + C$$$A
