Find the two functions f and g such that the lim x -> 0 f(x) and lim x -> 0 g(x) do not exist, but lim x -> 0 [f(x)+g(x)] does exist.

Even I split   lim   [f(x)+g(x)]   into   lim f(x) + lim g(x) x→0                              x→0         x→0   It does nothing as both   lim  f(x) AND lim  g(x) do not exist x→0          ... more
