integral of (sqrt(x)-x/2+2/(sqrt(x)))

Lösung

\int (x - \frac{x}{2} + \frac{2}{x}) d x

Lösung

\frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{2}}{4} + 4 x + C

Schritte zur Lösung

\int x - \frac{x}{2} + \frac{2}{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 x d x - \int \frac{x}{2} d x + \int \frac{2}{x} d x

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

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

\int \frac{2}{x} d x = 4 x

= \frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{2}}{4} + 4 x

Füge eine Konstante zur Lösung hinzu

= \frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{2}}{4} + 4 x + C
