Schritte zur Lösung

\int_{- 2}^{1} 3 x + 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_{- 2}^{1} 3 x d x + \int_{- 2}^{1} 4 d x

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

\int_{- 2}^{1} 4 d x = 12

= - \frac{9}{2} + 12

Vereinfache

- \frac{9}{2} + 12 : \frac{15}{2}

= \frac{15}{2}

\int_{0}^{2 π} 3 cos^{2} (θ) d θ

\int_{0}^{5} \frac{50}{x + 5} - 5 d x

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

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

\int_{0}^{12} 2000 - 12 t^{2} d t
