integral of (ln(x))/(x(1-ln^2(x)))

\int \frac{ln ( x )}{x ( 1 - ln ^{2} ( x ) )} d x

- \frac{1}{2} ln 1 - ln^{2} (x) + C

Solution steps

\int \frac{ln ( x )}{x ( 1 - ln ^{2} ( x ) )} d x

Apply u-substitution

= \int - \frac{1}{2 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= - \frac{1}{2} ln ∣ u ∣

Substitute back

u = 1 - ln^{2} (x)

= - \frac{1}{2} ln 1 - ln^{2} (x)

Add a constant to the solution

= - \frac{1}{2} ln 1 - ln^{2} (x) + C
