x (x^{2} - 1)^{2} : x^{5} - 2 x^{3} + x

= \int_{1}^{2} x^{5} - 2 x^{3} + x 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_{1}^{2} x^{5} d x - \int_{1}^{2} 2 x^{3} d x + \int_{1}^{2} x d x

\int_{1}^{2} x^{5} d x = \frac{21}{2}

\int_{1}^{2} 2 x^{3} d x = \frac{15}{2}

\int_{1}^{2} x d x = \frac{3}{2}

= \frac{21}{2} - \frac{15}{2} + \frac{3}{2}

Vereinfache

\frac{21}{2} - \frac{15}{2} + \frac{3}{2} : \frac{9}{2}

= \frac{9}{2}

\int_{2}^{4} 64 - x^{3} d x

\int_{2}^{5} (2 + 2 x) d x

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

\int_{0}^{2} 4 x^{2} e^{2 x} d x

\int_{1}^{2} (3 x^{2} - 5 x) d x
