Schritte zur Lösung

\int_{4}^{6} t^{2} - 2 t - 8 d t

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}^{6} t^{2} d t - \int_{4}^{6} 2 t d t - \int_{4}^{6} 8 d t

\int_{4}^{6} t^{2} d t = \frac{152}{3}

\int_{4}^{6} 2 t d t = 20

\int_{4}^{6} 8 d t = 16

= \frac{152}{3} - 20 - 16

Vereinfache

\frac{152}{3} - 20 - 16 : \frac{44}{3}

= \frac{44}{3}

\int_{0}^{x^{2}} sin (2 t) d t

\int_{0}^{1} ln (x^{2} + 5) d x

\int_{- 8}^{4} (- 2 x + 8) d x

\int_{0}^{3} (x^{2} - 9) d x

\int_{0}^{6} - 6 x^{2} - 18 x + 324 d x
