Schritte zur Lösung

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

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

\int_{- 2}^{1} 2 d y = 6

\int_{- 2}^{1} y d y = - \frac{3}{2}

\int_{- 2}^{1} y^{2} d y = 3

= 6 - (- \frac{3}{2}) - 3

Vereinfache

6 - (- \frac{3}{2}) - 3 : \frac{9}{2}

= \frac{9}{2}

\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

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

\int_{0}^{π} t^{2} d t
