integral of 1/(xln(x)+x)

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

ln ∣ ln (x) + 1 ∣ + C

Solution steps

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

Apply u-substitution

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

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

Apply u-substitution

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

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

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= ln ∣ v ∣

Substitute back

= ln ∣ ln (x) + 1 ∣

Add a constant to the solution

= ln ∣ ln (x) + 1 ∣ + C

\int (y^{2} - y^{3}) d y

\int - 4.15 x^{2} + 5.1 x + 6.096 d x

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

\int \frac{cos ( z )}{1 + sin ( z )} d z

\int 0.2 x + 1 d x
