(2 x - 1)^{2} : 4 x^{2} - 4 x + 1

= \int_{0}^{6} 4 x^{2} - 4 x + 1 d x

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}^{6} 4 x^{2} d x - \int_{0}^{6} 4 x d x + \int_{0}^{6} 1 d x

\int_{0}^{6} 4 x^{2} d x = 288

\int_{0}^{6} 4 x d x = 72

\int_{0}^{6} 1 d x = 6

= 288 - 72 + 6

Vereinfache

= 222

\int_{100}^{\infty} \frac{1}{x ^{2}} d x

\int_{x}^{8} t^{6} d t

\int_{0}^{1} 1 + x^{2} e^{x} d x

\int_{0}^{6} (e^{t} - e^{- t}) d t

\int_{1}^{3} x^{2} + 4 d x
