Schritte zur Lösung

\int_{0}^{7} 5 (1 - e^{y}) d y

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 5 \cdot \int_{0}^{7} 1 - e^{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

= 5 (\int_{0}^{7} 1 d y - \int_{0}^{7} e^{y} d y)

\int_{0}^{7} 1 d y = 7

\int_{0}^{7} e^{y} d y = e^{7} - 1

= 5 (7 - (e^{7} - 1))

= 5 (- e^{7} + 8)

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

\int_{0}^{1} (x e^{- x^{2}}) d x

\int_{0}^{1} 40 x (2 x^{2} + 1)^{4} d x

\int_{π}^{2 π} cos^{2} (x) d x

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