integral of (x/(sqrt(x-1)))

Lösung

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

Lösung

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

Schritte zur Lösung

\int \frac{x}{x - 1} d x

Wende U-Substitution an

= \int 2 (u^{2} + 1) d u

Entferne die Konstante:

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

= 2 \cdot \int u^{2} + 1 d u

Wende die Summenregel an:

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

= 2 (\int u^{2} d u + \int 1 d u)

\int u^{2} d u = \frac{u ^{3}}{3}

\int 1 d u = u

= 2 (\frac{u ^{3}}{3} + u)

Setze in

u = x - 1

ein

= 2 (\frac{( x - 1 ) ^{3}}{3} + x - 1)

Vereinfache

2 (\frac{( x - 1 ) ^{3}}{3} + x - 1) : 2 (\frac{1}{3} (x - 1)^{\frac{3}{2}} + x - 1)

= 2 (\frac{1}{3} (x - 1)^{\frac{3}{2}} + x - 1)

Füge eine Konstante zur Lösung hinzu
