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

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

ln ∣ 1 + ln (x) ∣ + C

Solution steps

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

Apply u-substitution

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

= \int \frac{1}{1 + u} 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 ∣ 1 + ln (x) ∣

Add a constant to the solution

= ln ∣ 1 + ln (x) ∣ + C

t^{2} y^{^{''}} - 3 t y^{^{'}} + 4 y = t^{\frac{5}{2}}

\frac{\partial}{\partial y} (x cos (yz))

\frac{d}{d x} (\frac{200}{x})

\int_{0}^{0.5} 100 x d x

\int \frac{( x + 9 )}{x ^{2} + 4} d x
