Schritte zur Lösung

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

\int_{0}^{2} x^{2} d x = \frac{8}{3}

\int_{0}^{2} 3 x d x = 6

= - \frac{8}{3} - 6

Vereinfache

- \frac{8}{3} - 6 : - \frac{26}{3}

= - \frac{26}{3}

\int_{0}^{x} e^{\frac{- t ^{2}}{2}} d t

\int_{0}^{5} x^{2} + 1 d x

\int_{0}^{5} x^{2} + 5 d x

\int_{0}^{3} π y^{\frac{2}{3}} d y

\int_{2 x}^{x^{5}} e^{- t^{2}} d t
