(x + 3)^{2} : x^{2} + 6 x + 9

= \int_{2}^{6} x^{2} + 6 x + 9 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}^{6} x^{2} d x + \int_{2}^{6} 6 x d x + \int_{2}^{6} 9 d x

\int_{2}^{6} x^{2} d x = \frac{208}{3}

\int_{2}^{6} 6 x d x = 96

\int_{2}^{6} 9 d x = 36

= \frac{208}{3} + 96 + 36

Vereinfache

\frac{208}{3} + 96 + 36 : \frac{604}{3}

= \frac{604}{3}

\int_{2 t}^{3 t} \frac{sin ( x )}{2 x} d x

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

\int_{- 2}^{0} x^{3} + x^{2} - 2 x d x

\int_{0}^{3} - 72 x^{- 3} d x

\int_{0}^{2} (6 x - 3) (8 x^{2} + 4) d x
