Schritte zur Lösung

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

\int_{1}^{4} x d x = \frac{14}{3}

\int_{1}^{4} x d x = \frac{15}{2}

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

= \frac{14}{3} - \frac{15}{2} + 6

Vereinfache

\frac{14}{3} - \frac{15}{2} + 6 : \frac{19}{6}

= \frac{19}{6}

\int_{0}^{1} (x + 2)^{3} d x

\int_{0}^{3} \frac{1}{( x + 5 ) ( x ^{2} + 9 )} d x

\int_{- 1}^{2} (3 x - 2) d x

\int_{1}^{\infty} \frac{2}{x ^{4}} d x

\int_{4}^{6} \frac{1}{( x - 4 ) ^{2}} d x
