Schritte zur Lösung

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

\int_{- 4}^{3} 12 d x = 84

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

\int_{- 4}^{3} x^{2} d x = \frac{91}{3}

= 84 - (- \frac{7}{2}) - \frac{91}{3}

Vereinfache

84 - (- \frac{7}{2}) - \frac{91}{3} : \frac{343}{6}

= \frac{343}{6}

\int_{1}^{2} \frac{1}{x ^{2}} - \frac{1}{x} d x

\int_{0}^{20} \frac{1}{16} x e^{- \frac{x}{4}} d x

\int_{0}^{\frac{1}{2}} 3 y d y

\int_{0}^{2} 3 t t^{2} + 1 d t

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