WebWhy should we prove that for all epsilon if we have a delta then the limit at that point (at which we have to prove the limit) is going to be equal to L (Here L =limf (x) x->a). We can just take the casewhen delta->0 and see whether the epsilon->0. WebTypically, an ɛ-δ proof begins with introducing ɛ and δ in that order. Since the definition gives ɛ the “For all” quantifier, it must remain arbitrary, so as repetitive as it sounds, every ɛ-δ proof starts with “Let ɛ > 0.”. Then followed by introducing δ = (insert variable expression here).

WebUsing the definition and by looking at the graph we see that f ( 1) = 1. As x goes to 0 from the right, we see that f ( x) is also approaching 0. Therefore lim x → 0 + f ( x) = 0. Note we cannot consider a left-hand limit at 0 as f is not defined for values of x < 0. Using the definition and the graph, f ( 0) = 0. Webwith epsilon and delta We will solve two problems which give examples of work-ing with the ,δ definitions of continuity and uniform con-tinuity. √Problem.
