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

= \int_{0}^{4} 16 t^{2} - 8 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} 16 t^{2} d t - \int_{0}^{4} 8 t d t + \int_{0}^{4} 1 d t

\int_{0}^{4} 16 t^{2} d t = \frac{1024}{3}

\int_{0}^{4} 8 t d t = 64

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

= \frac{1024}{3} - 64 + 4

Vereinfache

\frac{1024}{3} - 64 + 4 : \frac{844}{3}

= \frac{844}{3}

\int_{- 1}^{4} (x + 4) - (x^{2} - 2 x) d x

\int_{0}^{1} x^{\frac{5}{6}} d x

\int_{0}^{1} (x + 2 1 - x^{2}) d x

\int_{0}^{1} \frac{1}{4 + 5 x - 1} d x

\int_{0}^{5} \frac{x}{x ^{2} + 1} d x
