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

Lösung

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

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

Schritte zur Lösung

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

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

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

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

Vereinfache

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