integral of 1/(sqrt(x^2)-4)

\int \frac{1}{x ^{2} - 4} d x

ln ∣ x - 4 ∣ + C

Solution steps

\int \frac{1}{x ^{2} - 4} d x

x^{2} = (x),

assuming

x \geq 0

= \int \frac{1}{x - 4} 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 - 4

= ln ∣ x - 4 ∣

Add a constant to the solution

= ln ∣ x - 4 ∣ + C

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

\int 4 e^{- \frac{1}{2} x} d x

\int \frac{x + 1}{4 x ^{2} - x - 5} d x

\int \frac{6 x}{x ^{3} - 4 x ^{2} + x + 6} d x

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