integral of sqrt(x)(x^{3/2}+x)

Lösung

\int x (x^{\frac{3}{2}} + x) d x

Lösung

\frac{x ^{3}}{3} + \frac{2}{5} x^{\frac{5}{2}} + C

Schritte zur Lösung

\int x (x^{\frac{3}{2}} + x) d x

Multipliziere aus

x (x^{\frac{3}{2}} + x) : x^{2} + x^{\frac{3}{2}}

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

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

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

= \frac{x ^{3}}{3} + \frac{2}{5} x^{\frac{5}{2}}

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{3} + \frac{2}{5} x^{\frac{5}{2}} + C
