Digging in the wiki, I found this relation between 'arc-functions' and 'arc-functions-hyperbolics"
[tex]\\ arcsinh(x)= i \arcsin(-ix) \\ arccosh(x)= i \arccos(+ix) \\ arctanh(x)= i \arctan(-ix)[/tex] https://it.wikipedia.org/wiki/Funzioni_iperboliche#Funzioni_iperboliche_di_argomento_complesso
Happens that I never see in anywhere a relation between those functions. This relationship is correct?
