Schritte zur Lösung

\int_{0}^{2} - t^{2} + 3 t - 2 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_{0}^{2} t^{2} d t + \int_{0}^{2} 3 t d t - \int_{0}^{2} 2 d t

\int_{0}^{2} t^{2} d t = \frac{8}{3}

\int_{0}^{2} 3 t d t = 6

\int_{0}^{2} 2 d t = 4

= - \frac{8}{3} + 6 - 4

Vereinfache

- \frac{8}{3} + 6 - 4 : - \frac{2}{3}

= - \frac{2}{3}

\int_{0}^{4} (8 t - 1)^{2} d t

\int_{0}^{\frac{1}{2}} \frac{1}{( x - 1 ) ( x - 2 )} d x

\int_{- \infty}^{\infty} e^{- 4 x^{2}} d x

\int_{- 1}^{0} (2 x + 1)^{19} d x

\int_{- 1}^{1} (3 - 3 x^{2}) d x
