I would like to join the mathgroup list, please. The list was kind enough to solve a problem I had recently. I also have another urgent, and probably trivial (once you know how) problem: I have an equation eq:=f[x,y] I find the solution xm=x->g[y] which maximises f[x,y] for any y I now want to define this 'maximised' function of y only fy[y] I've tried: fy[y_]:=f[x,y]/.xm but this doesn't seem to recognise that I want the y s from xm to 'match' the y_ on the LHS. I'm also unclear as to whether I want := or = in the above line.
