Direction of the maximum gradient (scalar fields)

  1. Oct 14, 2014 #1
    If a question asks for the direction of the maximum gradient of a scalar field, is it acceptable to just use del(x) as the answer or is the question asking for a unit vector?
    Thanks

    Since the question is "in what direction", you could simply say "in the direction of" [itex]\nabla f[/itex]".
