integral of 1/(sqrt(x)*(\sqrt{x)+1)}

\int \frac{1}{x \cdot ( x + 1 )} d x

2 ln x + 1 + C

Solution steps

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

Apply u-substitution

= \int \frac{2}{u} d u

Take the constant out:

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

= 2 \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= 2 ln ∣ u ∣

Substitute back

u = x + 1

= 2 ln x + 1

Add a constant to the solution

= 2 ln x + 1 + C
