Lim as x->a f(x) = L PROOF using epsilon and delta

  1. Oct 10, 2010 #1
    Suppose limx->a f(x) = L does NOT equal 0.

    Prove that there exists a (delta) d > 0 such that 0<|x-a|<d

    which implies f(x) does NOT equal 0.

    Does Anybody Know the Proof For This?

    Your statement is incomplete.

    Make epsilon less = |L|.
