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

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

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

Solution steps

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

Apply u-substitution

: \int - u d u

= \int - u d u

Take the constant out:

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

= - \int u d u

Apply the Power Rule

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

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

Substitute back

u = ln (x + 1) - ln (x)

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

Add a constant to the solution

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

\int (x^{2} + e^{x}) d x

\int - 9 sin^{2} (x) d x

\int e^{x} (1 + e^{x})^{2} d x

\int \frac{8 sin ( x )}{x} d x

\int \frac{x ^{5} - 1}{x ^{4} - 1} d x
