What is associated with a gradient vector and a unit vector? Im looking at someones notes and trying to figure out what they are doing.

Question

Obviously, both are vectors.  The gradient vector does not necessarily have a length (magnitude) of 1, but a unit vector always has a length of 1.  

Your question is a bit vague.  Could you pinpoint what it is that you want to learn / know?

Could you take a photo of those notes and then share the image here on OpenStudy?  Otherwise I have little idea of what you are seeing in those notes.
