Best ResponseYou've already chosen the best response.0Is it generally true that \[\ln(a/b)=\ln(b/a)\] I have a case in which this equality is correct, but I don't know for sure if this holds for every a,b element of R. My case: \[\ln \left\frac{ c1 }{ c } \right=\ln \left\frac{ c }{ c1 } \right\]. I don't require a proof, just a simple explanation is fine.

Best ResponseYou've already chosen the best response.1the first one is correct. Since ln (a/b) = lna lnb and ln (b/a) = lnb lna hence ln(b/a) = lnb + lna = lna lnb = ln (a/b)

Best ResponseYou've already chosen the best response.0Yeah I knew about the particular case, not sure it was correct for every \[a,b \in \mathbb{R}\]. And apparently it does ;), thanks again. It seems like I'm becoming one of your regular customers!
