Schritte zur Lösung

\int_{0}^{1} \frac{2}{5} (x + 2) d x

Entferne die Konstante:

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

= \frac{2}{5} \cdot \int_{0}^{1} x + 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

= \frac{2}{5} (\int_{0}^{1} x d x + \int_{0}^{1} 2 d x)

\int_{0}^{1} x d x = \frac{1}{2}

\int_{0}^{1} 2 d x = 2

= \frac{2}{5} (\frac{1}{2} + 2)

\frac{2}{5} (\frac{1}{2} + 2) : 1

= 1

\int_{0}^{\frac{π}{4}} (cos (2 x))^{2} d x
