Lösung

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

6

Schritte zur Lösung

\int_{- 2}^{1} 3 + 2 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}^{1} 3 d x + \int_{- 2}^{1} 2 x d x

\int_{- 2}^{1} 3 d x = 9

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

= 9 - 3

= 6

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

\int_{\frac{1}{2}}^{1} (x^{- 3} - 18) d x

\int_{0}^{4} y e^{y} d y

\int_{0}^{\frac{π}{2}} 2 t d t

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