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

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

\frac{1}{ln ( x )} + C

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

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

Apply the Power Rule

= - (- \frac{1}{u})

Substitute back

u = ln (x)

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

Simplify

= \frac{1}{ln ( x )}

Add a constant to the solution

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