\int_{1}^{4} - 4 e^{x} d x

Entferne die Konstante:

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

= - 4 \cdot \int_{1}^{4} e^{x} d x

Wende U-Substitution an

= - 4 \cdot \int_{1}^{2} e^{u} \cdot 2 u d u

Entferne die Konstante:

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

= - 4 \cdot 2 \cdot \int_{1}^{2} e^{u} u d u

Wende die partielle Integration an

= - 4 \cdot 2 [e^{u} u - \int e^{u} d u]_{1}^{2}

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

= - 4 \cdot 2 [e^{u} u - e^{u}]_{1}^{2}

Vereinfache

= - 8 [e^{u} u - e^{u}]_{1}^{2}
