integral of (5ln(x^2))/x

\int \frac{5 ln ( x ^{2} )}{x} d x

5 ln^{2} (x) + C

Solution steps

\int \frac{5 ln ( x ^{2} )}{x} d x

Take the constant out:

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

= 5 \cdot \int \frac{ln ( x ^{2} )}{x} d x

Apply u-substitution

: \int \frac{ln ( u )}{2 u} d u

= 5 \cdot \int \frac{ln ( u )}{2 u} d u

Take the constant out:

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

= 5 \cdot \frac{1}{2} \cdot \int \frac{ln ( u )}{u} d u

Apply u-substitution

: \int v d v

= 5 \cdot \frac{1}{2} \cdot \int v d v

Apply the Power Rule

: \frac{v ^{2}}{2}

= 5 \cdot \frac{1}{2} \cdot \frac{v ^{2}}{2}

Substitute back

= 5 \cdot \frac{1}{2} \cdot \frac{ln ^{2} ( x ^{2} )}{2}

Simplify

5 \cdot \frac{1}{2} \cdot \frac{ln ^{2} ( x ^{2} )}{2} : 5 ln^{2} (x)

= 5 ln^{2} (x)

Add a constant to the solution

= 5 ln^{2} (x) + C

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

\int \frac{x + 2}{( x - 1 ) ^{2} ( x ^{2} + 4 )} d x

\int \frac{( x + 1 ) ^{6}}{2 x} d x

\int \frac{1}{5 x + x ( ln ( x ) ) ^{2}} d x

\int \frac{1}{2 x + 1} d x
