integral of 4(x-1)ln(x-1)

Lösung

\int 4 (x - 1) ln (x - 1) d x

Lösung

2 x^{2} ln (x - 1) - x^{2} + 2 x - 4 x ln (x - 1) + 2 ln (x - 1) - 1 + C

Schritte zur Lösung

\int 4 (x - 1) ln (x - 1) d x

Entferne die Konstante:

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

= 4 \cdot \int (x - 1) ln (x - 1) d x

(x - 1) ln (x - 1) : x ln (x - 1) - ln (x - 1)

= 4 \cdot \int x ln (x - 1) - ln (x - 1) d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 4 (\int x ln (x - 1) d x - \int ln (x - 1) d x)

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

\int ln (x - 1) d x = x ln (x - 1) - ln (x - 1) - x + 1

= 4 (\frac{1}{2} ln (x - 1) (x - 1)^{2} + x ln (x - 1) - ln (x - 1) - \frac{1}{4} (x - 1)^{2} - x + 1 - (x ln (x - 1) - ln (x - 1) - x + 1))

Vereinfache

4 (\frac{1}{2} ln (x - 1) (x - 1)^{2} + x ln (x - 1) - ln (x - 1) - \frac{1}{4} (x - 1)^{2} - x + 1 - (x ln (x - 1) - ln (x - 1) - x + 1)) : 2 x^{2} ln (x - 1) - x^{2} + 2 x - 4 x ln (x - 1) + 2 ln (x - 1) - 1

= 2 x^{2} ln (x - 1) - x^{2} + 2 x - 4 x ln (x - 1) + 2 ln (x - 1) - 1

Füge eine Konstante zur Lösung hinzu

= 2 x^{2} ln (x - 1) - x^{2} + 2 x - 4 x ln (x - 1) + 2 ln (x - 1) - 1 + C
