Schritte zur Lösung

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

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

\int_{1}^{4} \frac{2}{x} d x = 4 ln (2)

= \frac{15}{4} - 4 ln (2)

\int_{0}^{12} \frac{9}{12 - x} d x

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

\int_{0}^{1} \frac{8 t}{t ^{2} + 1} d t

\int_{0}^{\frac{π}{2}} cos (x + y) d y

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