\frac{7 - 4 x ^{3} + 6 x ^{6}}{x ^{6}} : \frac{7}{x ^{6}} - \frac{4}{x ^{3}} + 6

= \int \frac{7}{x ^{6}} - \frac{4}{x ^{3}} + 6 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{7}{x ^{6}} d x - \int \frac{4}{x ^{3}} d x + \int 6 d x

\int \frac{7}{x ^{6}} d x = - \frac{7}{5 x ^{5}}

\int \frac{4}{x ^{3}} d x = - \frac{2}{x ^{2}}

\int 6 d x = 6 x

= - \frac{7}{5 x ^{5}} - (- \frac{2}{x ^{2}}) + 6 x

Vereinfache

= - \frac{7}{5 x ^{5}} + \frac{2}{x ^{2}} + 6 x
