NEW FUNCTION

Function Expression :

\[f(x)=1+\frac{2ln x}{x} \]

Domain

\[\left]0, \infty\right[ \]

Limits

Integral

\[F(x) = x + \begin{cases} 0 & \text{for}\: \frac{1}{\left|{x}\right|} < 1 \wedge \left|{x}\right| < 1 \\\log{\left(x \right)}^{2} & \text{for}\: \left|{x}\right| < 1 \\\log{\left(\frac{1}{x} \right)}^{2} & \text{for}\: \frac{1}{\left|{x}\right|} < 1 \\2 {G_{3, 3}^{3, 0}\left(\begin{matrix} & 1, 1, 1 \\0, 0, 0 & \end{matrix} \middle| {x} \right)} + 2 {G_{3, 3}^{0, 3}\left(\begin{matrix} 1, 1, 1 & \\ & 0, 0, 0 \end{matrix} \middle| {x} \right)} & \text{otherwise} \end{cases} \]
