Schritte zur Lösung

\int_{1}^{2} t^{2} t^{3} + 1 d t

Wende U-Substitution an

= \int_{2}^{9} \frac{u}{3} d u

Entferne die Konstante:

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

= \frac{1}{3} \cdot \int_{2}^{9} u d u

Wende die Potenzregel an

= \frac{1}{3} [\frac{2}{3} u^{\frac{3}{2}}]_{2}^{9}

Berechne die Grenzen:

18 - \frac{4 2}{3}

= \frac{1}{3} (18 - \frac{4 2}{3})

Vereinfache

= \frac{54 - 4 2}{9}
