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

= \int_{0}^{1} 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_{0}^{1} x^{5} d x + \int_{0}^{1} 2 x^{3} d x + \int_{0}^{1} x d x

\int_{0}^{1} x^{5} d x = \frac{1}{6}

\int_{0}^{1} 2 x^{3} d x = \frac{1}{2}

\int_{0}^{1} x d x = \frac{1}{2}

= \frac{1}{6} + \frac{1}{2} + \frac{1}{2}

Vereinfache

\frac{1}{6} + \frac{1}{2} + \frac{1}{2} : \frac{7}{6}

= \frac{7}{6}

\int_{0}^{7} 9 x - x^{2} - 2 x d x

\int_{0}^{3} 3^{5 x} d x

\int_{e}^{e^{3}} \frac{ln ( x ^{3} )}{x} d x

\int_{0}^{1} 1 - e^{- x} d x
