When you get b / 0 , that indicates that the limit doesn't exist and is probably unbounded (an asymptote). In contrast, when you get 0 / 0 , that indicates that you don't have enough information to determine whether or not the limit exists, which is why it's called the indeterminate form. If you wind up here, you've got more work to do ... 1 Answer. Your suggested argument does not show that that the limit does not exist. The argument where lim x → af(x) = f(a) needs to hold is for continuity at a, not the limit existing. For instance, consider the function f(x): = {0, x ≠ 0 1, x = 0 Then lim x → 0f(x) exists, and equals to zero. It just happens to not agree with f(0), so ...To say that the limit doesn't exist at all just means that no L is the limit; so, the limit does not exist if " f(x) doesn't stay close enough to anything for large x ". To say this precisely, the limit of f(x) is L if for every ϵ > 0, there is a y so that whenever x > y, |f(x) − L| < ϵ (that is, for any desired amount of closeness, there ...1.
