\int_{0}^{4} e^{\frac{x}{2}} d x

Wende U-Substitution an

= \int_{0}^{2} e^{u} \cdot 2 d u

Entferne die Konstante:

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

= 2 \cdot \int_{0}^{2} e^{u} d u

Nutze das gemeinsame Integral :

\int e^{u} d u = e^{u}

= 2 [e^{u}]_{0}^{2}

Berechne die Grenzen:

e^{2} - 1

= 2 (e^{2} - 1)
