Schritte zur Lösung

\int_{0}^{1} x^{2} - 2 x + 8 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}^{1} x^{2} d x - \int_{0}^{1} 2 x d x + \int_{0}^{1} 8 d x

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

\int_{0}^{1} 2 x d x = 1

\int_{0}^{1} 8 d x = 8

= \frac{1}{3} - 1 + 8

Vereinfache

\frac{1}{3} - 1 + 8 : \frac{22}{3}

= \frac{22}{3}

\int_{1}^{2} \frac{e ^{x}}{x ^{2}} d x

\int_{0}^{t} x^{2} - 3 x + 2 d x

\int_{0}^{1} 2 - x - y d y

\int_{- 2}^{1} x - 6 ∣ x ∣ d x
