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

= \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

\int x^{3} (3 + x^{4})^{7} d x

\int cot (m x) csc^{2} (m x) d x

\int \frac{3 - 5 x + 7 x ^{2} + x ^{3}}{x ^{2}} d x

\int x^{5} ln (9 x^{3}) d x

\int (4 x + 8) d x
