Schritte zur Lösung

\int_{1}^{9} \frac{6}{x} d x

Entferne die Konstante:

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

= 6 \cdot \int_{1}^{9} \frac{1}{x} d x

Nutze das gemeinsame Integral :

\int \frac{1}{x} d x = ln (∣ x ∣)

= 6 [ln ∣ x ∣]_{1}^{9}

Berechne die Grenzen:

2 ln (3)

= 6 \cdot 2 ln (3)

Vereinfache

= 12 ln (3)

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

\int_{- 3}^{0} 3 + 9 - x^{2} d x

\int_{- 1}^{1} x^{2} e^{x^{3}} d x

\int_{0}^{π} 2 e^{x} - 7 cos (x) d x

\int_{- 3}^{6} (- \frac{2}{3} x + 5) d x
