Hallo,
die Grenzen eingesetzt:
=cosh(1) -sinh(1)≈ 0.3679
\( \begin{array}{ll}{u=\cosh (x)} & {v=x} \\ {u^{\prime}=\sinh (x)} & {; v^{\prime}=1}\end{array} \)
allgemein:
\( \int u' v dx=u v-\int u \cdot v^{\prime} d x \)
\( =\cos h(x) x-\int \cos h(x) \cdot 1 \cdot dx \)
\( =\cos h(x) \cdot x-\sinh (x)+c \)
