integral of (x-3)/((x-5)^3)

Lösung

\int \frac{x - 3}{( x - 5 ) ^{3}} d x

Lösung

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

Schritte zur Lösung

\int \frac{x - 3}{( x - 5 ) ^{3}} d x

Multipliziere aus

\frac{x - 3}{( x - 5 ) ^{3}} : \frac{x}{( x - 5 ) ^{3}} - \frac{3}{( x - 5 ) ^{3}}

= \int \frac{x}{( x - 5 ) ^{3}} - \frac{3}{( x - 5 ) ^{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{x}{( x - 5 ) ^{3}} d x - \int \frac{3}{( x - 5 ) ^{3}} d x

\int \frac{x}{( x - 5 ) ^{3}} d x = - \frac{1}{x - 5} - \frac{5}{2 ( x - 5 ) ^{2}}

\int \frac{3}{( x - 5 ) ^{3}} d x = - \frac{3}{2 ( x - 5 ) ^{2}}

= - \frac{1}{x - 5} - \frac{5}{2 ( x - 5 ) ^{2}} - (- \frac{3}{2 ( x - 5 ) ^{2}})

Vereinfache

- \frac{1}{x - 5} - \frac{5}{2 ( x - 5 ) ^{2}} - (- \frac{3}{2 ( x - 5 ) ^{2}}) : - \frac{1}{x - 5} - \frac{1}{( x - 5 ) ^{2}}

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