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 ...
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) …
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 …
