Schritte zur Lösung

\int_{0}^{1} 2 π x (33 - 33 x) d x

Entferne die Konstante:

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

= 2 π \cdot \int_{0}^{1} x (33 - 33 x) d x

Wende die partielle Integration an

= 2 π [\frac{1}{2} x^{2} (33 - 33 x) - \int - \frac{33 x ^{2}}{2} d x]_{0}^{1}

\int - \frac{33 x ^{2}}{2} d x = - \frac{11 x ^{3}}{2}

= 2 π [\frac{1}{2} x^{2} (33 - 33 x) - (- \frac{11 x ^{3}}{2})]_{0}^{1}

Vereinfache
