integral of 2((ln(x))^2)/x

\int 2 \frac{( ln ( x ) ) ^{2}}{x} d x

\frac{2}{3} ln^{3} (x) + C

Solution steps

\int 2 \cdot \frac{( ln ( x ) ) ^{2}}{x} d x

Take the constant out:

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

= 2 \cdot \int \frac{( ln ( x ) ) ^{2}}{x} d x

Apply u-substitution

: \int u^{2} d u

= 2 \cdot \int u^{2} d u

Apply the Power Rule

: \frac{u ^{3}}{3}

= 2 \cdot \frac{u ^{3}}{3}

Substitute back

u = ln (x)

= 2 \cdot \frac{ln ^{3} ( x )}{3}

Simplify

2 \cdot \frac{ln ^{3} ( x )}{3} : \frac{2}{3} ln^{3} (x)

= \frac{2}{3} ln^{3} (x)

Add a constant to the solution

= \frac{2}{3} ln^{3} (x) + C

\int (3 x^{3} + 5 x^{- 2} + 6 x^{2}) d x

\int \frac{1}{x ^{2} - 0.25} d x

\int 3 x^{2} - 2 x + 2 d x

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

\int sec^{- 3} (x) tan (x) d x
