integral of ((x^3-1))/(x^2(x-2)^3)

Lösung

\int \frac{( x ^{3} - 1 )}{x ^{2} ( x - 2 ) ^{3}} d x

Lösung

\frac{3}{16} ln ∣ x ∣ - \frac{1}{8 x} - \frac{3}{16} ln ∣ x - 2 ∣ - \frac{5}{4 ( x - 2 )} - \frac{7}{8 ( x - 2 ) ^{2}} + C

Schritte zur Lösung

\int \frac{x ^{3} - 1}{x ^{2} ( x - 2 ) ^{3}} d x

Ermittle den Partialbruch von

\frac{x ^{3} - 1}{x ^{2} ( x - 2 ) ^{3}} : \frac{3}{16 x} + \frac{1}{8 x ^{2}} - \frac{3}{16 ( x - 2 )} + \frac{5}{4 ( x - 2 ) ^{2}} + \frac{7}{4 ( x - 2 ) ^{3}}

= \int \frac{3}{16 x} + \frac{1}{8 x ^{2}} - \frac{3}{16 ( x - 2 )} + \frac{5}{4 ( x - 2 ) ^{2}} + \frac{7}{4 ( x - 2 ) ^{3}} 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

= \int \frac{3}{16 x} d x + \int \frac{1}{8 x ^{2}} d x - \int \frac{3}{16 ( x - 2 )} d x + \int \frac{5}{4 ( x - 2 ) ^{2}} d x + \int \frac{7}{4 ( x - 2 ) ^{3}} d x

\int \frac{3}{16 x} d x = \frac{3}{16} ln ∣ x ∣

\int \frac{1}{8 x ^{2}} d x = - \frac{1}{8 x}

\int \frac{3}{16 ( x - 2 )} d x = \frac{3}{16} ln ∣ x - 2 ∣

\int \frac{5}{4 ( x - 2 ) ^{2}} d x = - \frac{5}{4 ( x - 2 )}

\int \frac{7}{4 ( x - 2 ) ^{3}} d x = - \frac{7}{8 ( x - 2 ) ^{2}}

= \frac{3}{16} ln ∣ x ∣ - \frac{1}{8 x} - \frac{3}{16} ln ∣ x - 2 ∣ - \frac{5}{4 ( x - 2 )} - \frac{7}{8 ( x - 2 ) ^{2}}

Füge eine Konstante zur Lösung hinzu

= \frac{3}{16} ln ∣ x ∣ - \frac{1}{8 x} - \frac{3}{16} ln ∣ x - 2 ∣ - \frac{5}{4 ( x - 2 )} - \frac{7}{8 ( x - 2 ) ^{2}} + C
