RandVars
RandVars[ n ]
RandVars[ n ] returns a list of n different single-letter variables. If n is 1, a single variable is returned rather than a singleton list. Certain variable names like “v”, “q”, “o” and “i” are never chosen because they look very similar to other mathematical symbols and might confuse students.
