10

Schritte zur Lösung

\int_{1}^{3} 1 + 2 y 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_{1}^{3} 1 d y + \int_{1}^{3} 2 y d y

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

\int_{1}^{3} 2 y d y = 8

= 2 + 8

\int_{0}^{4} \frac{36}{x ^{2} + 9} d x

\int_{0}^{π} \frac{1}{4 x ^{2} - 4 x + 5} d x

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

\int_{1}^{3} \frac{2}{5 + 3 x} d x

\int_{- 1}^{1} e^{- \frac{x ^{2}}{2}} d x
