Schritte zur Lösung

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

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

\int_{0}^{4} 2 x d x = 16

= - \frac{64}{3} + 16

Vereinfache

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

= - \frac{16}{3}

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

\int_{0}^{1} sin (n \cdot π \cdot x) d x

\int_{1}^{2} 20 x^{3} + \frac{6}{x ^{2}} d x

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

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