\(f(x)=cosh(x)=\frac{1}{2}*(e^{x}+e^{-x})=\frac{1}{2}*(\frac{e^{2x}+1}{e^{x}})\)
Allgemein Volumen bei Rotation um die x-Achse:
\(V=π*\int\limits_{a}^{b}(f(x))^{2}dx\)
\((f(x))^{2}=\frac{1}{4}*(\frac{e^{4x}+2*e^{2x}+1}{e^{2x}})\)
\(V=\frac{π}{4}*\int\limits_{0}^{1}(\frac{e^{4x}+2*e^{2x}+1}{e^{2x}})dx\)
