What is the integral of-5x^2ln(-2/3 x) ?

The integral of-5x^2ln(-2/3 x) is -5(1/3 x^3ln(-2/3 x)-(x^3)/9)+C

integral of-5x^2ln(-2/3 x)

\int - 5 x^{2} ln (- \frac{2}{3} x) d x

- 5 (\frac{1}{3} x^{3} ln (- \frac{2}{3} x) - \frac{x ^{3}}{9}) + C

Solution steps

\int - 5 x^{2} ln (- \frac{2}{3} x) d x

Take the constant out:

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

= - 5 \cdot \int x^{2} ln (- \frac{2}{3} x) d x

Apply Integration By Parts

= - 5 (\frac{1}{3} x^{3} ln (- \frac{2}{3} x) - \int \frac{x ^{2}}{3} d x)

\int \frac{x ^{2}}{3} d x = \frac{x ^{3}}{9}

= - 5 (\frac{1}{3} x^{3} ln (- \frac{2}{3} x) - \frac{x ^{3}}{9})

Add a constant to the solution

= - 5 (\frac{1}{3} x^{3} ln (- \frac{2}{3} x) - \frac{x ^{3}}{9}) + C

\int t cos (n wt) d t

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

\int \frac{1 - sin ( t )}{t + cos ( t )} d t

\int \frac{1}{( 5 t + 1 ) ^{2} - 1} d t

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