Schritte zur Lösung

\int_{0}^{2} x e - \frac{x ^{2} - 1}{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

= \int_{0}^{2} x e d x - \int_{0}^{2} \frac{x ^{2} - 1}{2} d x

\int_{0}^{2} x e d x = e 2

\int_{0}^{2} \frac{x ^{2} - 1}{2} d x = \frac{1}{3}

= e 2 - \frac{1}{3}

\int_{- 10}^{10} t d t

\int_{0}^{π} (sin (x) - 8 x^{3}) d x

\int_{x}^{1} 24 x (1 - y) d y

\int_{1}^{3} 4 x^{2} (x - 1) d x

\int_{0}^{π} (x^{2} + 3 x) cos (x) d x
