Good question. You don't need an extra dimension just for the resultant
vector, and you might just add up the individual vectors to draw the
resultant, all within n dimensions. But insofar as "seeing it" requires
an outside observer -- you cannot "see" a path on a two dimensional
surface unless you rise above this surface in a third dimension --,
another dimension becomes necessary.
