Schritte zur Lösung

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

\int_{1}^{2} 4 d x = 4

= - \frac{7}{3} + 4

Vereinfache

- \frac{7}{3} + 4 : \frac{5}{3}

= \frac{5}{3}

\int_{0}^{2} 3 4 x d x

\int_{0}^{2} e^{- x^{2}} x d x

\int_{1}^{3} \frac{x ^{3}}{x} d x

\int_{0}^{\frac{π}{4}} x \cdot sin (x) d x

\int_{0}^{10} \frac{1}{10 - x} d x
