integral of (ln(x))/((x))

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

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

Solution steps

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

Apply u-substitution

: \int u d u

= \int u d u

Apply the Power Rule

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

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

Substitute back

u = ln (x)

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

Add a constant to the solution

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

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

\int \frac{1}{( a ^{2} + y ^{2} ) ^{\frac{3}{2}}} d y

\int \frac{t ^{4} + 4}{t ^{4}} d t

\int sin^{3} (x) cos^{2} (y) d x

\int 1 + x^{2} (x^{3}) d x
