Schritte zur Lösung

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

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{1}^{8} \frac{1}{t} d t

Nutze das gemeinsame Integral :

\int \frac{1}{t} d t = ln (∣ t ∣)

= 2 [ln ∣ t ∣]_{1}^{8}

Berechne die Grenzen:

3 ln (2)

= 2 \cdot 3 ln (2)

= 6 ln (2)

\int_{0}^{1} b (a^{4 k - 1})

\int_{0}^{2} 2 e^{x^{2} - 3 x} d x

\int_{0}^{4} x^{2} \cdot \frac{x}{8} d x

\int_{0}^{4} 2 π x (2 x) d x

\int_{0}^{x^{4}} e^{- 2 t} d t
