Schritte zur Lösung

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

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

\int_{- 1}^{1} 3 d x = 6

= \frac{2}{3} + 6

Vereinfache

\frac{2}{3} + 6 : \frac{20}{3}

= \frac{20}{3}

\int_{- 32}^{32} 5 x^{2} d x

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

\int_{0}^{6} e^{- \frac{1}{3} x} d x

\int_{0}^{l n (2)} e^{x - y} d y

\int_{2}^{5} \frac{1}{( x - 1 ) \cdot ( x + 2 )} d x
