Question

help me with delta epsula definition of continutity

Answer 1

you meant
\[E \subset \mathbb{R}, f:E \rightarrow \mathbb{R}\]
\[x \in E : |x - x _{0}|<\delta \rightarrow |f(x) - f(x_{0})|<\epsilon\]
\[\delta \rightarrow 0, and \epsilon \rightarrow 0\]

Answer 2

we have to choose \[\xi\] first

Answer 3

ξ is some very small value :) what's problem?)
