x - (x - 2)^{2} : - x^{2} + 5 x - 4

= \int_{1}^{4} - x^{2} + 5 x - 4 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}^{4} x^{2} d x + \int_{1}^{4} 5 x d x - \int_{1}^{4} 4 d x

\int_{1}^{4} x^{2} d x = 21

\int_{1}^{4} 5 x d x = \frac{75}{2}

\int_{1}^{4} 4 d x = 12

= - 21 + \frac{75}{2} - 12

Vereinfache

- 21 + \frac{75}{2} - 12 : \frac{9}{2}

= \frac{9}{2}

\int_{\frac{π}{4}}^{\frac{3 π}{4}} 1

\int_{- π}^{π} sin (2 x) sin (x) d x

\int_{- 1}^{1} 4 x^{2} + 7 d x

\int_{0}^{4} 6 e^{2 t} d t

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