Mathematica can solve it: just type Solve[y Log[x] == (1 - x), x] The result is in terms of the ProductLog, aka the Lambert W function, a built-in function. regards, alan "Bernard Bourée" <bernard at bouree.net> wrote in message news:bps4gf$9uj$1 at smc.vnet.net... > I 'm trying to find a way to solve the equation > > y = (1-x)/ Log(x) > > How can I find x when y is known ? > > Is there a numerical method ? > with series development? > > -- > Bernard Bourée > bernard at bouree.net
