I would like to suppress the argument [0, 0, 0, 0] of K in the output of

Normal[Series[
K[(Subscript[x, 0] - Subscript[x, 0] 0) t +
Subscript[x, 0] 0, (Subscript[x, 1] - Subscript[x, 1] 0) t +
Subscript[x, 1] 0, (Subscript[x, 2] - Subscript[x, 2] 0) t +
Subscript[x, 2] 0, (Subscript[x, 3] - Subscript[x, 3] 0) t +
Subscript[x, 3] 0], {t, 0, 2}]] /. t -> 1


• You probably want the derivative to look nice. (basing on your last question). Try this

• I think that the superscript notation is better in this case. Dec 17, 2014 at 14:32

• @simon The underscore is called Blank in Wolfram Language and it stands for any expression. You could also use % /. whatever_[0, 0, 0, 0] -> whatever to get the same output. This tutorial gives a nice introduction to the basics of pattern. Dec 18, 2014 at 11:16
