Schritte zur Lösung

\int_{- 1}^{1} x^{2} + 4 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}^{1} x^{2} d x + \int_{- 1}^{1} 4 d x

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

\int_{- 1}^{1} 4 d x = 8

= \frac{2}{3} + 8

Vereinfache

\frac{2}{3} + 8 : \frac{26}{3}

= \frac{26}{3}

\int_{0}^{5} 4 - 10 e^{- 0.2 x} d x

\int_{\frac{π}{6}}^{\frac{π}{3}} cos (2 x) d x

\int_{0}^{10} 2000 - 12 x^{2} d x

\int_{2}^{3} 5^{3 x} d x

\int_{0}^{x} e^{- 3 x} d x
