I want to plot 2 points {1,1,1} and {2,2,2} using ListPointPlot3D and Tooltip, labelling each point "a" and "b" respectively. ListPointPlot3D[Tooltip[{{1, 1, 1}, {2, 2, 2}}, {"a", "b"}]] doesn't seem to work (it displays "{a,b}" at both points) Thanks for any help...

Hi, perhaps some of you have 'struggled' in the past with subscripted or subsuperscripted variables. To my opinion and observation most Mathematica users do not exploit the potential of the Mathematica notation. As I had noticed Mathematica code and output would (sometimes) look much nicer andhttps://groups.google.com/d/topic/comp.soft-sys.math.mathematica/rhIhi-v_D5E

Some compiled functions yield reals even if the input and necessary output are integers. How can I force the output to be an integer rather than a real in such cases?

I'm looking for a neat formula to find the center of a circle in 3D through 3 points. I also need a good way to display it, preferably thickened so I can show several and see whether they are linked, etc. To my surprise I did not find anything on the Wolfram sites about these problems.

It is a scoping issue which is why the approach that uses explicit parameters in f works. Alternatively, deconflict the symbols Clear[a, b, c, f, soln]; f[x_] = (a*x + b)*x + c; soln[aa_, bb_, cc_] = Module[{x}, x /. Solve[f[x] == 0, x] /. {a -> aa, b -> bb, c -> cc}]; soln[a,https://groups.google.com/d/topic/comp.soft-sys.math.mathematica/XNroGf09PZY
