Interesting typographical issue here (I won't respond to the issue of using primed variables). TraditionalForm[f'] gives an entirely pleasing, raised prime. TraditionalForm[f''] does, too. TraditionalForm[f'''] gives an appealing rendering of f with a superscript (3).

It would be much better if the \[Prime] character were raised to the normal level to give better looking expressions. I admit that there could be some visual confusion, but not Mathematica confusion, with derivatives, but it would usually be clear from context. > > I wish that WRI would fix the Prime, DoublePrime, ReversePrime and ReverseDoublePrime characters so they displayed at the correct vertical level in expressions. > > David Park > djmp at earthlink.net > http://home.earthlink.net/~djmp/ > > > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
