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

Nutze das gemeinsame Integral :

\int \frac{1}{x ^{2} + 1} d x = arctan (x)

= [arctan (x)]_{0}^{3}

Berechne die Grenzen:

arctan (3)

= arctan (3)

\int_{e^{- 1}}^{e^{1}} ∣ ln (x) ∣ d x

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

\int_{0}^{2 - y} x d x

\int_{5}^{8} \frac{1}{x} d x
