integral of (ln(k))/k

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

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

Solution steps

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

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 (k)

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

Add a constant to the solution

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

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

\int (\frac{x - x}{3}) d x

\int \frac{7 x - 1}{x ^{2} + x - 2} d x

\int \frac{4 - x}{4 - x ^{2}} d x

\int 30 csc (5 x) sec (5 x) d x
