integral of (ln(x))/x

integral

\frac{ln ( x )}{x}

\frac{ln ^{2} ( x )}{2} + C

Solution steps

\int \frac{ln ( x )}{x} d x

Apply u-substitution

= \int u d u

Apply the Power Rule

= \frac{u ^{2}}{2}

Substitute back

u = ln (x)

= \frac{ln ^{2} ( x )}{2}

Add a constant to the solution

= \frac{ln ^{2} ( x )}{2} + C
