Schritte zur Lösung

\int_{4}^{7} 28 - 11 x + x^{2} 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_{4}^{7} 28 d x - \int_{4}^{7} 11 x d x + \int_{4}^{7} x^{2} d x

\int_{4}^{7} 28 d x = 84

\int_{4}^{7} 11 x d x = \frac{363}{2}

\int_{4}^{7} x^{2} d x = 93

= 84 - \frac{363}{2} + 93

Vereinfache

84 - \frac{363}{2} + 93 : - \frac{9}{2}

= - \frac{9}{2}

\int_{- 3}^{3} 1 9 - x^{2} d x

\int_{0}^{\frac{π}{7}} sec (x) tan (x) d x

\int_{5}^{s} (t - t^{2})^{8} d t

\int_{1}^{e} \frac{1 + x}{x} d x

\int_{0}^{40} 3000 e^{0.04 t} d t
