integral of (ln(x))^3

\int (ln (x))^{3} d x

x ln^{3} (x) - 3 (x ln^{2} (x) - 2 (x ln (x) - x)) + C

Solution steps

\int (ln (x))^{3} d x

Apply Integration By Parts

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

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

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

= x ln^{3} (x) - 3 (x ln^{2} (x) - 2 (x ln (x) - x))

Add a constant to the solution

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

f (x) = x^{2} + 3 x - 1, at x = 1

y^{^{''}} - 4 = 0

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

6 y^{^{'}} - y = 9 x^{- 3 x}, y (0) = 4

\frac{2 x + 4}{3 x + 7}, at - 2
