Schritte zur Lösung

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

Wende U-Substitution an

= \int_{2}^{0} - \frac{u ^{2}}{2} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{0}^{2} - \frac{u ^{2}}{2} d u

Entferne die Konstante:

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

= - (- \frac{1}{2} \cdot \int_{0}^{2} u^{2} d u)

Wende die Potenzregel an

= - (- \frac{1}{2} [\frac{u ^{3}}{3}]_{0}^{2})

Vereinfache

= \frac{1}{2} [\frac{u ^{3}}{3}]_{0}^{2}

Berechne die Grenzen:

\frac{8}{3}

= \frac{1}{2} \cdot \frac{8}{3}
