I want Mathematica to compute v[0] and it is supposed to give t1 (ie. t sub 1). I typed in v[0] but Mathematica gives me 01 (i.e., 0 sub 1). Obviously it is not the correct answer. Can anyone give me some insight of this delima? Thanks a lot.
Since my posting didn't appear to appear I post again
Instead of using the notation packet I prefer to use fixed strings. Typo
looks the same
v[t_]:=t+Subscript["t",1]
v[3]
Cell[BoxData[
RowBox[{"3", "+",
SubscriptBox["\<\"t\"\>", "1"]}]], "Output",
CellLabel->"Out[5]="]
The string "t" cannot be confused with the pattern name in t_.
