Integral de $$$\frac{1}{2 x}$$$
Calculadora relacionada: Calculadora de integrales definidas e impropias
Tu entrada
Halla $$$\int \frac{1}{2 x}\, dx$$$.
Solución
Aplica la regla del factor constante $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ con $$$c=\frac{1}{2}$$$ y $$$f{\left(x \right)} = \frac{1}{x}$$$:
$${\color{red}{\int{\frac{1}{2 x} d x}}} = {\color{red}{\left(\frac{\int{\frac{1}{x} d x}}{2}\right)}}$$
La integral de $$$\frac{1}{x}$$$ es $$$\int{\frac{1}{x} d x} = \ln{\left(\left|{x}\right| \right)}$$$:
$$\frac{{\color{red}{\int{\frac{1}{x} d x}}}}{2} = \frac{{\color{red}{\ln{\left(\left|{x}\right| \right)}}}}{2}$$
Por lo tanto,
$$\int{\frac{1}{2 x} d x} = \frac{\ln{\left(\left|{x}\right| \right)}}{2}$$
Añade la constante de integración:
$$\int{\frac{1}{2 x} d x} = \frac{\ln{\left(\left|{x}\right| \right)}}{2}+C$$
Respuesta
$$$\int \frac{1}{2 x}\, dx = \frac{\ln\left(\left|{x}\right|\right)}{2} + C$$$A
