9

Schritte zur Lösung

\int_{0}^{3} 3 + 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_{0}^{3} 3 d y + \int_{0}^{3} 2 y d y - \int_{0}^{3} y^{2} d y

\int_{0}^{3} 3 d y = 9

\int_{0}^{3} 2 y d y = 9

\int_{0}^{3} y^{2} d y = 9

= 9 + 9 - 9

Vereinfache

= 9

\int_{0}^{1} \frac{2 x + 3}{x ^{2} + 1} d x

\int_{0}^{1} (9 x^{e} + 4 e^{x}) d x

\int_{0}^{8} 2 x - (x - 4) d x

\int_{0}^{8} x^{2} - 6 x + 8 d x

\int_{e}^{e^{2}} (\frac{1}{x ln ( x )}) d x
