This article was designed to explain what exactly an epsilon-delta proof is and to demonstrate an example of such a proof. Although these proofs are of lit- tle practical use, they still offer key insight into what a limit actually is. In addition, they often require mathematical creativit...

Learn the definition of Epsilon delta proof and browse a collection of 28 enlightening community discussions around the topic.
Epsilon-delta proofs define a limit to lie within an interval as small as possible, thereby guaranteeing that the function stays close to the undefined point, even though the point is never reached by the function. Why do we need the epsilon-delta definition of a limit?
Using the precise definition of a limit (epsilon and delta), prove as x approaches -3, the limit (1 - 4x) = 13.Epsilon Delta ProofsLike many statements in mathematics, we can prove that a limit equals a specific value. The way we do so is called an ...
Discover the Epsilon Delta Definition of a Limit, fundamental in understanding calculus concepts like continuity and differentiation.
For many of my students, Real Analysis I is the first, and only, analysis course they will ever take, and these students tend to be overwhelmed by epsilon-delta proofs. To help them I reordered Real Analysis I to start with an "Analysis Boot Camp" in the first 2 weeks of class, ...

We can prove by using the continuity of $\ln n$ function that $\;\lim\limits_{n\to\infty}\dfrac{\log_an}n=0\;$ However, this problem appears in my problems book quite early right after the definition of $\epsilon$-language definition of limit of a... arsenaler Thread Jun 23, ...
particularly in `epsilon-delta' proofs in limit theory (as in the differential calculus). The termdeltais often used, oncehas been mentioned, to mean a quantity that is slightly bigger thanepsilonbut still very small. "The cost isn't epsilon, but it's delta" means that the cost isn't ...
