Schritte zur Lösung

\int_{1}^{2} \frac{5}{t} d t

Entferne die Konstante:

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

= 5 \cdot \int_{1}^{2} \frac{1}{t} d t

Nutze das gemeinsame Integral :

\int \frac{1}{t} d t = ln (∣ t ∣)

= 5 [ln ∣ t ∣]_{1}^{2}

Berechne die Grenzen:

ln (2)

= 5 ln (2)

\int_{- 1}^{2} [x] d x

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

\int_{0}^{2 π} 3 cos (t) d t

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

\int_{- 1}^{0} (x^{\frac{1}{3}} - x) d x
