Dear All, I am new to Mathematica. I am trying to recursively solve equation and saving the values into Table. Since I need the real solutions only so I use Reduce. The following is my code: f = 5.68672 T + 6.46776 T^3 t = Table[i, {i, 0.2, 3, 0.2}] sols = Table[Reduce[f == t[[i]], T, Reals], {i, Length[t]}] {T == 0.0351204, T == 0.06995, T == 0.104221, T == 0.137708, T == 0.170237, T == 0.201687, T == 0.231988, T == 0.26111, T == 0.289058, T == 0.315857, T == 0.34155, T == 0.366188, T == 0.389828, T == 0.412529, T == 0.434347} The solution is OK as I compared it to other software as well. The only thing that matters me is how to remove the T== , i.e. I just need the solution and then to copy this into another table, say sols2 that contains sols2 = {0.0351204, 0.06995, 0.104221, T == 0.137708,.., 0.434347} I tried the following: sols2 = T/.sols but produce the following error: sols2 = ReplaceAll::reps: ... is neither a list of replacement rules nor a valid dispatch table, and so cannot be used for replacing. >> Does anyone know how to remove the T==? Thank you, Wayan
