Schritte zur Lösung

\int_{2}^{3} x^{2} + 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_{2}^{3} x^{2} d x + \int_{2}^{3} 2 d x

\int_{2}^{3} x^{2} d x = \frac{19}{3}

\int_{2}^{3} 2 d x = 2

= \frac{19}{3} + 2

Vereinfache

\frac{19}{3} + 2 : \frac{25}{3}

= \frac{25}{3}

\int_{2}^{3} \frac{9}{( 3 x + 2 ) ^{4}} d x

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

\int_{0}^{2 π} 1 - cos (2 x) d x

\int_{0}^{1} (x^{2} - 2 x + 7) d x

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