Schritte zur Lösung

\int_{0}^{1} z 1 - z^{2} d z

Wende U-Substitution an

= \int_{1}^{0} - u^{2} d u

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

= - \int_{0}^{1} - u^{2} d u

Entferne die Konstante:

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

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

Wende die Potenzregel an

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

Vereinfache

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

Berechne die Grenzen:
