Calc III Question ? *****


Show that the following limit does not exist.
                                             2
                                            x  + y
                                 lim        -------
                            x, y -> (0, 0)   2    2
                                            x  + y 
The limit does not exist because:
  • The limits along the path y=a x depend on a.
  • The limits along the path y=a x^3 depend on a.
  • The limits along the path y=a x^4 depend on a.
  • Limits of the form 0/0 are not defined and do not exist.
  • The limits along the path y=a x^2 depend on a.
