 Attempt to formally generalize log, exp functions to 3,4,5..(n,m) log exp JmsNxn Long Time Fellow Posts: 465 Threads: 85 Joined: Dec 2010 04/14/2011, 11:16 PM (This post was last modified: 04/14/2011, 11:16 PM by JmsNxn.) I think the easiest proof is $f(x^y) = f(x)f(y) = f(y^x)$ which can only be true for a constant function. bo198214 Administrator Posts: 1,391 Threads: 90 Joined: Aug 2007 04/15/2011, 07:29 AM (04/14/2011, 11:16 PM)JmsNxn Wrote: I think the easiest proof is $f(x^y) = f(x)f(y) = f(y^x)$ which can only be true for a constant function. But this would need a bit more explanation *why* constancy follows from that. And then its not that short anymore « Next Oldest | Next Newest »
