→ suhorng :應該是 ...forall δ>0 there exists...s.t...才對 03/02 00:51
→ bjiyxo :回樓上，我只看過原po的寫法沒看過你的 03/02 01:37
→ THEJOY :最後應該是 for some x with 0<|x-a|<δ ? 03/02 02:20
※ 引述《yosifu ()》之銘言：
: Without using any negative words,
: state what it means to say that the limit of f(x),
: as x approaches a, is not L.
Orginal statement:
For all ε>0, there is δ > 0 so that |f(x) - L| < ε
whenever 0 < |x - a| < δ.
Negation of the original statement:
There is ε > 0, for all δ > 0 so that |f(x) - L| >= ε
whenever 0 < |x - a| < δ.
