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

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

\int_{- 2}^{2} 2 d x = 8

= \frac{16}{3} + 8

Vereinfache

\frac{16}{3} + 8 : \frac{40}{3}

= \frac{40}{3}

\int_{- 5}^{10} e^{- 0.05 x} d x

\int_{- 2}^{1} 2 - y - y^{2} d y

\int_{0}^{l n (2 x)} sin (5 e^{t}) d t

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

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