12

Schritte zur Lösung

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

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

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

= 3 + 9

= 12

\int_{0}^{\frac{π}{2}} ∣ 6 sin (x) - 6 cos (2 x) ∣ d x

\int_{0}^{6} 6 x d x

\int_{0}^{x} 9 t e^{3 t} d t

\int_{0}^{0.64} ln (1 + x) d x

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