Schritte zur Lösung

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

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

\int_{0}^{2} x^{2} d x = \frac{8}{3}

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

= 4 + \frac{8}{3} + 2

Vereinfache

4 + \frac{8}{3} + 2 : \frac{26}{3}

= \frac{26}{3}

\int_{0}^{1} \frac{x ^{15}}{x ^{8} + 1} d x

\int_{0}^{1} (1 - x^{4})^{7} d x

\int_{1}^{4} (2 x - 1)^{5} d x

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

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