Schritte zur Lösung

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

\int_{2}^{3} x^{3} d x = \frac{65}{4}

\int_{2}^{3} x d x = \frac{5}{2}

= \frac{65}{4} + \frac{5}{2}

Vereinfache

\frac{65}{4} + \frac{5}{2} : \frac{75}{4}

= \frac{75}{4}

\int_{0}^{4} (1 + \frac{x}{2}) d x

\int_{1}^{4} \frac{u - 5}{u} d u

\int_{- 1}^{3} \frac{x ^{3} - 1}{x ^{3} + x} d x

\int_{0}^{2} 6 x^{5} e^{x^{3} y} d y

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