Schritte zur Lösung

\int_{- 4}^{0} x^{2} + 4 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_{- 4}^{0} x^{2} d x + \int_{- 4}^{0} 4 x d x

\int_{- 4}^{0} x^{2} d x = \frac{64}{3}

\int_{- 4}^{0} 4 x d x = - 32

= \frac{64}{3} - 32

Vereinfache

\frac{64}{3} - 32 : - \frac{32}{3}

= - \frac{32}{3}

\int_{- π}^{0} - 2 cos^{2} (x) sin (x) d x

\int_{0}^{10} 25 - (t - 5)^{2} d t

\int_{2}^{5} (x^{3} - x^{2} + 8) d x

\int_{0}^{4} - x^{2} - 3 x d x

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