Note

Funzione non qualificato (cosh) viene utilizzato per eseguire il calcolo. Se tale funzione non è disponibile, std::cosh viene utilizzato a causa di ricerca tesi a carico.

Original:

Unqualified function (cosh) is used to perform the computation. If such function is not available, std::cosh is used due to argument dependent lookup.
