integral of 1/(tln(t))

\int \frac{1}{t ln ( t )} d t

ln ∣ ln (t) ∣ + C

Solution steps

\int \frac{1}{t ln ( t )} d t

Apply u-substitution

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = ln (t)

= ln ∣ ln (t) ∣

Add a constant to the solution

= ln ∣ ln (t) ∣ + C
