Wende U-Substitution an

= \int_{0}^{1} cosh (u) a d u

Entferne die Konstante:

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

= a \cdot \int_{0}^{1} cosh (u) d u

Nutze das gemeinsame Integral :

\int cosh (u) d u = sinh (u)

= a [sinh (u)]_{0}^{1}

Berechne die Grenzen:

\frac{e ^{2} - 1}{2 e}

= a \frac{e ^{2} - 1}{2 e}
