Schritte zur Lösung

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

\int_{0}^{4} 3 x^{2} d x = 64

\int_{0}^{4} x d x = \frac{16}{3}

= 64 + \frac{16}{3}

Vereinfache

64 + \frac{16}{3} : \frac{208}{3}

= \frac{208}{3}

\int_{- π}^{π} x^{2} \cdot cos (n x) d x

\int_{- 1}^{3} 2 x - x^{2} + 3 d x

\int_{1}^{4} (x^{2} + 4 x^{3} + 10) d x

\int_{0}^{1} 4 x + 7 d x

\int_{0}^{2 y} e^{x + y} d x
