If f : R → R is a function, then we write limx→a f(x) = L to mean: ∀ > 0 ∃δ > 0 ∀x ( (0 < |x − a| < δ) → (|f(x) − L| < ) ). (The universe for all variables is R.) a) Find the negation of the definition above (using similar quantifier notation). b) Use your answer to a) to prove that for all L ∈ R, the statement limx→0 sin(1/x) = L is false.
