\int_{2}^{4} 2 x - \frac{8}{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_{2}^{4} 2 x d x - \int_{2}^{4} \frac{8}{x} d x

\int_{2}^{4} 2 x d x = 12

\int_{2}^{4} \frac{8}{x} d x = 8 ln (2)

= 12 - 8 ln (2)

\int_{3}^{5} 6 x - 18 d x

\int_{0}^{2 π} e^{- 2 i θ} d θ

\int_{e}^{6} (\frac{1}{x} + \frac{1}{1 + x}) d x

\int_{0}^{3} ∣ 5 x - 8 ∣ d x

\int_{0}^{\infty} \frac{2}{3 + x ^{2}} d x
