Mathematica 5 gives the following: In[2]:= Solve[y == (1 - x)/Log[x], x] Out[2]= {{x -> y*ProductLog[E^(1/y)/y]}} -- Steve Luttrell West Malvern, UK "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 > >
