Schritte zur Lösung

\int_{0}^{2} x^{2} - 6 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}^{2} x^{2} d x - \int_{0}^{2} 6 x d x + \int_{0}^{2} 8 d x

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

\int_{0}^{2} 6 x d x = 12

\int_{0}^{2} 8 d x = 16

= \frac{8}{3} - 12 + 16

Vereinfache

\frac{8}{3} - 12 + 16 : \frac{20}{3}

= \frac{20}{3}

\int_{0}^{3} (2 x + sin (2 π x)) d x

\int_{0}^{π} e^{x^{2}} sin (x) d x

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

\int_{- 1.5}^{x} \frac{1}{4} d x

\int_{0}^{1} ln (2) + y d y
