[This post has been delayed due to email problems - moderator] I have this function f[x_, om_, oro_] := 1/(Sqrt[oro] - Sqrt[om(1 + x)^3 + ol + oro]) /. ol -> myrule and I want to define a rule (myrule) so that f[0,om,or0]=1 If I set myrule=-om + (-1 + Sqrt[oro])^2 - oro; then it works find when I do not give numerical values to om and oro. For instance, if I evaluate f[0,a,b] I get 1, but if I evaluate f[0,0.3,0.4] I get 3.77485. I think it is just because it is not taking the right which is convenient for me. Can you help me? Thanks, Ruth
