What if the symbol doesn't exist?
Hi, I'm trying to use a symbol (the script E, not capital E) but I can't find it anywhere on on the list of symbols. I guess that it doesn't exist as defaults in Mathematica 4. Are there any ways I can install new symbols? On a separate issue, are there any ways I can I can use a variable with subscript? For example x with subscript y mean one variable not Subscript[x,y] Thanks, Vinh
