\int_{1}^{2} \frac{x ^{4} + 5 x ^{3}}{x ^{2}} d x

\frac{x ^{4} + 5 x ^{3}}{x ^{2}} = x^{2} + 5 x

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

\int_{1}^{2} 5 x d x = \frac{15}{2}

= \frac{7}{3} + \frac{15}{2}

Vereinfache

\frac{7}{3} + \frac{15}{2} : \frac{59}{6}

= \frac{59}{6}

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

\int_{2}^{4} (x^{2}) d x

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

\int_{0}^{1} e^{- 2 x} cos (3 x) d x

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