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

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

arcsin (ln (x)) + C

Solution steps

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

Apply u-substitution

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

Use the common integral:

\int \frac{1}{1 - u ^{2}} d u = arcsin (u)

= arcsin (u)

Substitute back

u = ln (x)

= arcsin (ln (x))

Add a constant to the solution

= arcsin (ln (x)) + C
