Schritte zur Lösung

\int_{2}^{4} x^{2} + 3 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}^{4} x^{2} d x + \int_{2}^{4} 3 d x

\int_{2}^{4} x^{2} d x = \frac{56}{3}

\int_{2}^{4} 3 d x = 6

= \frac{56}{3} + 6

Vereinfache

\frac{56}{3} + 6 : \frac{74}{3}

= \frac{74}{3}

\int_{0}^{\frac{1}{8}} x ln (8 x) d x

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

\int_{- 1}^{1} e^{x^{4}} d x

\int_{0}^{2} 4 x^{2} + x + 5 d x

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