Integral de $$$\frac{a}{v}$$$ con respecto a $$$v$$$

Halla $$$\int \frac{a}{v}\, dv$$$.

Aplica la regla del factor constante $$$\int c f{\left(v \right)}\, dv = c \int f{\left(v \right)}\, dv$$$ con $$$c=a$$$ y $$$f{\left(v \right)} = \frac{1}{v}$$$:

$${\color{red}{\int{\frac{a}{v} d v}}} = {\color{red}{a \int{\frac{1}{v} d v}}}$$

La integral de $$$\frac{1}{v}$$$ es $$$\int{\frac{1}{v} d v} = \ln{\left(\left|{v}\right| \right)}$$$:

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

Por lo tanto,

$$\int{\frac{a}{v} d v} = a \ln{\left(\left|{v}\right| \right)}$$

Añade la constante de integración:

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

$$$\int \frac{a}{v}\, dv = a \ln\left(\left|{v}\right|\right) + C$$$A
