integral of (x-5)ln(x)

\int (x - 5) ln (x) d x

ln (x) (\frac{x ^{2}}{2} - 5 x) - \frac{1}{2} (\frac{x ^{2}}{2} - 10 x) + C

Solution steps

\int (x - 5) ln (x) d x

Apply Integration By Parts

: ln (x) (\frac{x ^{2}}{2} - 5 x) - \int \frac{1}{2} (x - 10) d x

= ln (x) (\frac{x ^{2}}{2} - 5 x) - \int \frac{1}{2} (x - 10) d x

\int \frac{1}{2} (x - 10) d x = \frac{1}{2} (\frac{x ^{2}}{2} - 10 x)

= ln (x) (\frac{x ^{2}}{2} - 5 x) - \frac{1}{2} (\frac{x ^{2}}{2} - 10 x)

Add a constant to the solution

= ln (x) (\frac{x ^{2}}{2} - 5 x) - \frac{1}{2} (\frac{x ^{2}}{2} - 10 x) + C

\int \frac{e ^{\frac{1}{z}}}{z ^{2}} d z

y = 3 - 4 x^{2}, (- 1, - 1)

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

\int 8 sin (x) cos (x) d x

\frac{d}{d x} (- 4 e^{2 x})
