(8 t - 1)^{2} : 64 t^{2} - 16 t + 1

= \int_{0}^{4} 64 t^{2} - 16 t + 1 d t

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{4} 64 t^{2} d t - \int_{0}^{4} 16 t d t + \int_{0}^{4} 1 d t

\int_{0}^{4} 64 t^{2} d t = \frac{4096}{3}

\int_{0}^{4} 16 t d t = 128

\int_{0}^{4} 1 d t = 4

= \frac{4096}{3} - 128 + 4

Vereinfache

\frac{4096}{3} - 128 + 4 : \frac{3724}{3}

= \frac{3724}{3}
