Schritte zur Lösung

\int_{- 7}^{4} - x^{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_{- 7}^{4} x^{2} d x - \int_{- 7}^{4} 3 x d x

\int_{- 7}^{4} x^{2} d x = \frac{407}{3}

\int_{- 7}^{4} 3 x d x = - \frac{99}{2}

= - \frac{407}{3} - (- \frac{99}{2})

Vereinfache

- \frac{407}{3} - (- \frac{99}{2}) : - \frac{517}{6}

= - \frac{517}{6}

\int_{2}^{4} e^{- s t} d t

\int_{1}^{9} \frac{2 ln ( x )}{x} d x

\int_{- 3}^{3} (- x^{2} + 9) d x

\int_{2}^{5} \frac{3}{x} d x

\int_{- 8}^{8} x^{3} d x
