integral of 1/(ln(x+2))

\int \frac{1}{ln ( x + 2 )} d x

Ei (ln (x + 2)) + C

Solution steps

\int \frac{1}{ln ( x + 2 )} d x

Apply u-substitution

= \int \frac{1}{ln ( u )} d u

Apply u-substitution

= \int \frac{e ^{v}}{v} d v

Use the nonelementary integral:

\int \frac{e ^{x}}{x} d x = Ei (x)

= Ei (v)

Substitute back

= Ei (ln (x + 2))

Add a constant to the solution

= Ei (ln (x + 2)) + C

\int [3 x^{2} + sin (3 x)] d x

\int x (x + 3) (x + 1) d x

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

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

\int 5 x (x^{2} + 6) d x
