Integraal van $$$\frac{\sqrt{\frac{\ln\left(x\right)}{x}}}{\sqrt{x \ln\left(x\right)}}$$$
Gerelateerde rekenmachine: Rekenmachine voor bepaalde en oneigenlijke integralen
Uw invoer
Bepaal $$$\int \frac{\sqrt{\frac{\ln\left(x\right)}{x}}}{\sqrt{x \ln\left(x\right)}}\, dx$$$.
Oplossing
De invoer is herschreven: $$$\int{\frac{\sqrt{\frac{\ln{\left(x \right)}}{x}}}{\sqrt{x \ln{\left(x \right)}}} d x}=\int{\frac{1}{x} d x}$$$.
De integraal van $$$\frac{1}{x}$$$ is $$$\int{\frac{1}{x} d x} = \ln{\left(\left|{x}\right| \right)}$$$:
$${\color{red}{\int{\frac{1}{x} d x}}} = {\color{red}{\ln{\left(\left|{x}\right| \right)}}}$$
Dus,
$$\int{\frac{1}{x} d x} = \ln{\left(\left|{x}\right| \right)}$$
Voeg de integratieconstante toe:
$$\int{\frac{1}{x} d x} = \ln{\left(\left|{x}\right| \right)}+C$$
Antwoord
$$$\int \frac{\sqrt{\frac{\ln\left(x\right)}{x}}}{\sqrt{x \ln\left(x\right)}}\, dx = \ln\left(\left|{x}\right|\right) + C$$$A
