\int_{1}^{7} t^{2} - 2 t - 15 d t

Entferne die Extremwerte

= \int_{1}^{5} - t^{2} + 2 t + 15 d t + \int_{5}^{7} t^{2} - 2 t - 15 d t

\int_{1}^{5} - t^{2} + 2 t + 15 d t = \frac{128}{3}

\int_{5}^{7} t^{2} - 2 t - 15 d t = \frac{56}{3}

= \frac{128}{3} + \frac{56}{3}

Vereinfache

\frac{128}{3} + \frac{56}{3} : \frac{184}{3}

= \frac{184}{3}
