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

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

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

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int \frac{1}{u ^{2}} d u

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

Apply the Power Rule

: - \frac{1}{u}

= - 2 (- \frac{1}{u})

Substitute back

u = ln (x)

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

Simplify

- 2 (- \frac{1}{ln ( x )}) : \frac{2}{ln ( x )}

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

Add a constant to the solution

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

\int \frac{3 ln ( x ^{2} )}{x} d x

\int \frac{1 - x}{1 + 4 x ^{2}} d x

\int \frac{x}{x + 10} d x

\int \frac{1}{sin ^{2} ( w ) 1 - cot ( w )} d w

\int \frac{81 x ^{3}}{4 9 x ^{2} + 16} d x
