Schritte zur Lösung

\int_{1}^{3} \frac{5}{x} d x

Entferne die Konstante:

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

= 5 \cdot \int_{1}^{3} \frac{1}{x} d x

Nutze das gemeinsame Integral :

\int \frac{1}{x} d x = ln (∣ x ∣)

= 5 [ln ∣ x ∣]_{1}^{3}

Berechne die Grenzen:

ln (3)

= 5 ln (3)

\int_{- 2}^{5} 5 d x

\int_{- 3}^{2} b x - a x^{2} d x

\int_{0}^{\infty} x^{2} e^{\frac{- x}{2}} d x

\int_{0}^{1} e^{- ik x} d x

\int_{- 1}^{1} (x^{4} - x^{6}) d x
