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
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?
