Schritte zur Lösung

\int_{1}^{5} 2 x^{2} - 12 x + 10 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_{1}^{5} 2 x^{2} d x - \int_{1}^{5} 12 x d x + \int_{1}^{5} 10 d x

\int_{1}^{5} 2 x^{2} d x = \frac{248}{3}

\int_{1}^{5} 12 x d x = 144

\int_{1}^{5} 10 d x = 40

= \frac{248}{3} - 144 + 40

Vereinfache

\frac{248}{3} - 144 + 40 : - \frac{64}{3}

= - \frac{64}{3}

\int_{0}^{1} x^{2} - 4 x + 8 d x

\int_{1}^{2} \frac{8 - 2 x}{x ^{3}} d x

\int_{0}^{4} 32 - 2 x^{2} d x

\int_{17}^{x} \frac{1}{t} d t

\int_{x}^{1} sin^{2} (t) d t
