Homework Help: Showing differentiability in R^n

  1. Sep 21, 2006 #1
    When you are given a function and asked for differentiability at a point in domain or the whole domain, what's the normal procedure? I think the definition is almost useless in here...
    Also, I'm still stuck on the previous questions so if anyone bothers to check them out...

    The definition is entirely useful, and the previous question has already been answered.
