Okay my apologizes to continue this TERRIBLY OFF TOPIC thread but something has to be set straight here. The above is a limit - it doesn't prove that 0/0=a. In a slightly better form, since people are always abusing things likes limits and infiinites heres the definition.:
DEFINITION Let f be a function defined on some open interval that contains a number a, except possibly a itself. Then we say that the limit of f(x) as x approaches a is L, and we write lim f(x) = L x->a if for every number E > 0 there is a corresponding number d >0 such that |f(x) - L| < E whenever 0 < |x-a| < d From this you should see that your "proof" fails.
