integral of 1/((x-a))

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

ln ∣ x - a ∣ + C

Solution steps

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

Apply u-substitution

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

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = x - a

= ln ∣ x - a ∣

Add a constant to the solution

= ln ∣ x - a ∣ + C

\int a^{2} - u^{2} d u

\int e^{- 2 x} 2 x d x

\int sin^{2} (r) cos^{3} (r) d r

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

\int 9 e^{6 y} d y
