With Mathematica version 6, you may now use the form Table[expr, {i, {i1, i2,...,ik}}] in order to specify a particular list of values for the iterator i instead of a regularly incremented list. For example: f[x_] := x^(-3) Cos[2 x] f1[x_] = f'[x]; f2[x_] = f''[x]; info=Table[N@{x, f[x], f1[x], f2[x]}, {x, {-3, 1, 1/2, Pi, -5}}]; headers = TraditionalForm /@ {HoldForm[x],HoldForm[f[x]],HoldForm[f'[x]],HoldForm[f''[x]]}; TableForm[info,TableHeadings->{None,headers}] Derek wrote: > I am just beginning to learn to use Mathematica, and need to create a table of values. I would like to be able to input x-values and have the table display f(x), f'(x), and possibly f''(x) for a given function.

Is there a way to specify a list of specific x values so that Mathematica computes the values of f[x] in table form? > > Any help would be greatly, greatly appreciated.
