Homework Help: Homogeneous function of degree n

  1. Oct 1, 2011 #1
    1. The problem statement, all variables and given/known data
    See photo


    2. Relevant equations



    3. The attempt at a solution
    I am learning partial differential and never be taught about homongeneous function.
    What is this? How to solve the problem?

    I finally figure out how to do part a.
    See my work on the photo.

    Part b is similar to part a except 1 step.
    That is, I need to prove [itex]f_{xy}[/itex]=[itex]f_{yx}[/itex]

    It seems the question doesn't provide enough equation for me to do this.
