Lösung

\int \frac{x ^{\frac{- 3}{2}} + x - 7}{x} d x

- \frac{1}{x} + \frac{2}{3} x^{\frac{3}{2}} - 14 x + C

Schritte zur Lösung

\int \frac{x ^{\frac{- 3}{2}} + x - 7}{x} d x

\frac{x ^{\frac{- 3}{2}} + x - 7}{x} = (\frac{x ^{\frac{- 3}{2}}}{x} + \frac{x}{x} - \frac{7}{x})

= \int \frac{x ^{\frac{- 3}{2}}}{x} + \frac{x}{x} - \frac{7}{x} 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 ^{\frac{- 3}{2}}}{x} d x + \int \frac{x}{x} d x - \int \frac{7}{x} d x

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

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

\int \frac{7}{x} d x = 14 x

= - \frac{1}{x} + \frac{2}{3} x^{\frac{3}{2}} - 14 x
