integral of 1/(x-25)

Solution

\int \frac{1}{x - 25} d x

Solution

ln ∣ x - 25 ∣ + C

Solution steps

\int \frac{1}{x - 25} 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 - 25

= ln ∣ x - 25 ∣

Add a constant to the solution

= ln ∣ x - 25 ∣ + C
