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

Lösung

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

Lösung

ln ∣ x - 3 ∣ - \frac{6}{x - 3} - \frac{9}{2 ( x - 3 ) ^{2}} + C

Schritte zur Lösung

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

Wende U-Substitution an

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

Multipliziere aus

\frac{( u + 3 ) ^{2}}{u ^{3}} : \frac{1}{u} + \frac{6}{u ^{2}} + \frac{9}{u ^{3}}

= \int \frac{1}{u} + \frac{6}{u ^{2}} + \frac{9}{u ^{3}} 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

= \int \frac{1}{u} d u + \int \frac{6}{u ^{2}} d u + \int \frac{9}{u ^{3}} d u

\int \frac{1}{u} d u = ln ∣ u ∣

\int \frac{6}{u ^{2}} d u = - \frac{6}{u}

\int \frac{9}{u ^{3}} d u = - \frac{9}{2 u ^{2}}

= ln ∣ u ∣ - \frac{6}{u} - \frac{9}{2 u ^{2}}

Setze in

u = x - 3

ein

= ln ∣ x - 3 ∣ - \frac{6}{x - 3} - \frac{9}{2 ( x - 3 ) ^{2}}
