\frac{1}{12} c

Schritte zur Lösung

\int_{0}^{1} c x^{2} (1 - x) d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= c \cdot \int_{0}^{1} x^{2} (1 - x) d x

x^{2} (1 - x) : x^{2} - x^{3}

= c \cdot \int_{0}^{1} x^{2} - 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

= c (\int_{0}^{1} x^{2} d x - \int_{0}^{1} x^{3} d x)

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} x^{3} d x = \frac{1}{4}

= c (\frac{1}{3} - \frac{1}{4})

Füge

\frac{1}{3} - \frac{1}{4}

zusammen:

\frac{1}{12}

= \frac{1}{12} c
