To continue the handwaving some more then :)

y = (8 + 9.592) /2 = 8.796 This means e^x = 8.796 => x = ln(8.796) = 2.174 -- --Moby They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin First they came for the Jews and I did not speak out because I was not a Jew.
