Schritte zur Lösung

\int_{- 7}^{0} 1 + 49 - 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_{- 7}^{0} 1 d x + \int_{- 7}^{0} 49 - x^{2} d x

\int_{- 7}^{0} 1 d x = 7

\int_{- 7}^{0} 49 - x^{2} d x = \frac{49 π}{4}

= 7 + \frac{49 π}{4}

\int_{4}^{7} \frac{2 x}{8 - x} d x

\int_{x}^{0} e^{- 10 t} d t

\int_{0}^{1} cos (w x) d x

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

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