Schritte zur Lösung

\int_{0}^{1} sin^{2} (2 π x) d x

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int_{0}^{1} \frac{1}{2} (1 - cos (4 π x)) d x

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int_{0}^{1} 1 - cos (4 π x) 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{1}{2} (\int_{0}^{1} 1 d x - \int_{0}^{1} cos (4 π x) d x)

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

\int_{0}^{1} cos (4 π x) d x = 0

= \frac{1}{2} (1 - 0)
