real analysis - Understanding the definition of Cauchy sequence ...
My question is related with the definition of Cauchy sequence As we know that a sequence $(x_n)$ of real numbers is called Cauchy, if for every positive real number ε, there is a positive integer ...
Overview of basic facts about Cauchy functional equation
Also a few other equations related to this equation are often studied. (Equations which can be easily transformed to Cauchy functional equation or can be solved by using similar methods.) Is there some …
I would like to know an intuitive way to understand a Cauchy sequence ...
Apr 30, 2017 · Since you asked specifically how to understand Cauchy sequences "intuitively" (rather than how to do $\epsilon,\delta$ proofs with them), I would say that the best way to understand them …
Proving that a sequence $|a_n|\\leq 1/n$ is Cauchy.
0 You know that every convergent sequence is a Cauchy sequence (it is immediate regarding to the definitions of both a Cauchy sequence and a convergent sequence). Your demonstration of the …

What is the difference between Cauchy and convergent sequence?
One important difference is the way the notion is defined: the notion of Cauchy sequence only refers to the terms of the sequence itself, while the notion of convergent sequence refers to (the existence of) …
