Schritte zur Lösung

\int_{- 1}^{0} x - 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}^{0} x d x - \int_{- 1}^{0} x^{3} d x

\int_{- 1}^{0} x d x = - \frac{1}{2}

\int_{- 1}^{0} x^{3} d x = - \frac{1}{4}

= - \frac{1}{2} - (- \frac{1}{4})

Vereinfache

- \frac{1}{2} - (- \frac{1}{4}) : - \frac{1}{4}

= - \frac{1}{4}

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

\int_{1}^{3} (t^{2} - t + 6) d t

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

\int_{0}^{1} (x^{4} - x^{3}) d x

\int_{0}^{8} \frac{12}{x + 1} d x
