integral of 1/(xsqrt(ln(x)+1))

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

2 ln (x) + 1 + C

Solution steps

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

Apply u-substitution

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

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

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 2 u^{\frac{1}{2}}

Substitute back

u = ln (x) + 1

= 2 (ln (x) + 1)^{\frac{1}{2}}

Apply radical rule:

= 2 ln (x) + 1

Add a constant to the solution

= 2 ln (x) + 1 + C

\int 5 x e^{- 2 x^{2}} d x

\int 9 x^{2} x^{3} + 1 d x

\int \frac{4 x ^{2}}{( x ^{2} - 9 ) ^{\frac{3}{2}}} d x

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