Entferne die Extremwerte

= \int_{- 2}^{0} t^{3} - 9 t d t + \int_{0}^{3} - t^{3} + 9 t d t + \int_{3}^{4} t^{3} - 9 t d t

\int_{- 2}^{0} t^{3} - 9 t d t = 14

\int_{0}^{3} - t^{3} + 9 t d t = \frac{81}{4}

\int_{3}^{4} t^{3} - 9 t d t = \frac{49}{4}

= 14 + \frac{81}{4} + \frac{49}{4}

Vereinfache

14 + \frac{81}{4} + \frac{49}{4} : \frac{93}{2}

= \frac{93}{2}
