Schritte zur Lösung

\int_{4}^{3} sin (x) d x

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{3}^{4} sin (x) d x

Nutze das gemeinsame Integral :

\int sin (x) d x = - cos (x)

= - [- cos (x)]_{3}^{4}

Berechne die Grenzen:

- cos (4) + cos (3)

= - (- cos (4) + cos (3))

= cos (4) - cos (3)

\int_{0}^{1} 2^{x} \cdot 3^{x} d x
