integral of sqrt(x+1)+2/3 x

Lösung

\int x + 1 + \frac{2}{3} x d x

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

Schritte zur Lösung

\int x + 1 + \frac{2}{3} 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 + 1 d x + \int \frac{2}{3} x d x

\int x + 1 d x = \frac{2}{3} (x + 1)^{\frac{3}{2}}

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

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

Füge eine Konstante zur Lösung hinzu

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