integral of 1/(3(x-2))

\int \frac{1}{3 ( x - 2 )} d x

\frac{1}{3} ln ∣ x - 2 ∣ + C

Solution steps

\int \frac{1}{3 ( x - 2 )} d x

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{x - 2} d x

Apply u-substitution

= \frac{1}{3} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{3} ln ∣ u ∣

Substitute back

u = x - 2

= \frac{1}{3} ln ∣ x - 2 ∣

Add a constant to the solution

= \frac{1}{3} ln ∣ x - 2 ∣ + C
