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

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

\int_{0}^{2} x^{3} d x = 4

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

= 4 - 2

Vereinfache

= 2

\int_{0}^{t} \frac{1}{1 + x ^{2}} d x

\int_{0}^{1} 4 x arctan (x) d x

\int_{1}^{4} e^{- x} + \frac{ln ( x )}{x} d x

\int_{0}^{1} lo g_{e} (x) d x

\int_{3}^{5} \frac{1}{x ^{2} - 4 x + 8} d x
