I'd like to be able to occasionally use all the letters of the alphabet
(or at least the first 12 or so), both small and capital letters, for
variables. I think it's the easiest way to present a lot of formulas. I
was able to Unprotect everything except "I", which Mathematica reserves
for the "imaginary unity", "i". Is there any way to temporarily
unprotect "I"?
(Also, I wish there was some way to copy the example from my notebook
without all the extraneous back-slashes, etc.)
What I get from Mathematica is as follows:
Unprotect[I]
Protect::locked: "Symbol \[ImaginaryI] is locked.
Attributes[I]
{Locked, Protected, ReadProtected}
ClearAttributes[I, Locked]
Attributes::locked: Symbol \[ImaginaryI] is locked.
Clear[I]
Clear::wrsym: Symbol \[ImaginaryI] is Protected.
ClearAll[I]
ClearAll::"wrsym": "Symbol \[ImaginaryI] is Protected."
Any help appreciated.
