integral of x^3(x^4+1)

Lösung

\int x^{3} (x^{4} + 1) d x

Lösung

\frac{x ^{8}}{8} + \frac{x ^{4}}{4} + C

Schritte zur Lösung

\int x^{3} (x^{4} + 1) d x

Multipliziere aus

x^{3} (x^{4} + 1) : x^{7} + x^{3}

= \int x^{7} + x^{3} 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^{7} d x + \int x^{3} d x

\int x^{7} d x = \frac{x ^{8}}{8}

\int x^{3} d x = \frac{x ^{4}}{4}

= \frac{x ^{8}}{8} + \frac{x ^{4}}{4}

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{8}}{8} + \frac{x ^{4}}{4} + C
