Schritte zur Lösung

\int_{2}^{6} 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_{2}^{6} x^{2} d x - \int_{2}^{6} 3 x d x

\int_{2}^{6} x^{2} d x = \frac{208}{3}

\int_{2}^{6} 3 x d x = 48

= \frac{208}{3} - 48

Vereinfache

\frac{208}{3} - 48 : \frac{64}{3}

= \frac{64}{3}

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

\int_{0}^{\frac{π}{2}} sec^{3} (x) d x

\int_{1}^{2} x^{2} + x^{- 2} d x

\int_{- 7}^{0} \frac{2}{x ^{\frac{2}{3}}} d x

\int_{0}^{π} (9 e^{x} + 9 sin (x)) d x
