integral of 1/((x-1))

\int \frac{1}{( x - 1 )} d x

ln ∣ x - 1 ∣ + C

Solution steps

\int \frac{1}{x - 1} d x

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 = x - 1

= ln ∣ x - 1 ∣

Add a constant to the solution

= ln ∣ x - 1 ∣ + C
