Schritte zur Lösung

\int_{0}^{1} t 1 + 36 t^{2} d t

Wende U-Substitution an

= \int_{1}^{37} \frac{u}{72} d u

Entferne die Konstante:

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

= \frac{1}{72} \cdot \int_{1}^{37} u d u

Wende die Potenzregel an

= \frac{1}{72} [\frac{2}{3} u^{\frac{3}{2}}]_{1}^{37}

Berechne die Grenzen:

\frac{74 37}{3} - \frac{2}{3}

= \frac{1}{72} (\frac{74 37}{3} - \frac{2}{3})
