Here is a sample function: f[x_] := x^2 Sin[x] Assuming you have Version 6, you can make a table simply by listing the set of values you want. (values = Table[{x, f[x], f'[x], f''[x]} // N, {x, {0, 1, 1.5, 2, 5, 10}}]) // TableForm If you don't have Version 6 you can use MapThread with a pure function. (But for a beginner this take a little study. You would have to look up Function and MapThread in Help.) Going back to Version 6, we can add a heading row and then display a formatted grid. (gridarray = Join[{{x, HoldForm[f[x]], HoldForm[f'[x]], HoldForm[f''[x]]}}, values]) // TableForm Grid[gridarray, Frame -> True, Dividers -> {{2 -> Black}, {2 -> Black}}] David Park djmpark at comcast.net http://home.comcast.net/~djmpark From: Derek [mailto:derekcashel at yahoo.com] 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. I have already specified the function, and I have found the following input creates tables: Table[{x,f[x]},{x,-5,5,.5}] My problem is this: I would like to input specifc x-values, rather than use set intervals as defined in {x,-5,5,.5} above. 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. Thanks.
