Calc III Question
Show that the following limit does not exist.
2 x y f(x, y) = ------- 2 4 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^(1/2) 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.
