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

Vereinfache

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

\int_{0}^{2} 2 x^{2} d x = \frac{16}{3}

\int_{0}^{2} 4 x d x = 8

= \frac{16}{3} - 8

Vereinfache

\frac{16}{3} - 8 : - \frac{8}{3}

= - \frac{8}{3}

\int_{- 8}^{7} (1 - x) d x

\int_{- 1}^{0} \frac{1}{1 + e ^{t}} d t

\int_{0}^{\frac{1}{2}} x^{2} e^{6 x} d x

\int_{- 2}^{2} 28 - 7 x^{2} d x

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