\frac{500}{3} c

Schritte zur Lösung

\int_{0}^{10} c (10 x - x^{2}) d x

Entferne die Konstante:

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

= c \cdot \int_{0}^{10} 10 x - x^{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

= c (\int_{0}^{10} 10 x d x - \int_{0}^{10} x^{2} d x)

\int_{0}^{10} 10 x d x = 500

\int_{0}^{10} x^{2} d x = \frac{1000}{3}

= c (500 - \frac{1000}{3})

Füge

500 - \frac{1000}{3}

zusammen:

\frac{500}{3}

= \frac{500}{3} c

\int_{- 2}^{3} x^{3} - 7 x + 2 d x

\int_{- 1}^{1} (3 x + 2) d x

\int_{0}^{π} x^{3} sin (3 x) d x

\int_{1}^{4} (- 3 x) d x

\int_{0}^{4} \frac{1}{( x - 1 ) ^{\frac{1}{3}}} d x
