Schritte zur Lösung

\int_{3}^{4} - x^{3} + 7 x^{2} - 12 x 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_{3}^{4} x^{3} d x + \int_{3}^{4} 7 x^{2} d x - \int_{3}^{4} 12 x d x

\int_{3}^{4} x^{3} d x = \frac{175}{4}

\int_{3}^{4} 7 x^{2} d x = \frac{259}{3}

\int_{3}^{4} 12 x d x = 42

= - \frac{175}{4} + \frac{259}{3} - 42

Vereinfache

- \frac{175}{4} + \frac{259}{3} - 42 : \frac{7}{12}

= \frac{7}{12}

\int_{0}^{\infty} x ln (x) d x

\int_{- 5}^{0} 0 d x

\int_{1}^{2} ln (1 + x) d x

\int_{0}^{8} \frac{1}{2} x d x

\int_{- 3}^{3} \frac{2}{3} 9 - x^{2} d x
