- 希腊字母epsilon的两种写法ϵ，ε，一般认为哪个是原型，哪个是变体？ - 知乎
希腊字母epsilon的两种写法ϵ，ε，一般认为哪个是原型，哪个是变体？ 我一直以为前者是原型，因为TeX中两者分别记为\epsilon，\varepsilon 但在Microsoft Word的数学公式输入器中却将两者分别… 显示全部 关注者 86
- What does the letter epsilon signify in mathematics?
The greek letter epsilon, written ϵ ϵ or ε ε, is just another variable, like x x, n n or T T Conventionally it's used to denote a small quantity, like an error, or perhaps a term which will be taken to zero in some limit It's possible that you are confusing it with the set membership symbol ∈ ∈, which is something different When you see x ∈ X x ∈ X it means that X X is a set

The symbol is called "epsilon," and is simply a variable, just like x x or y y However, note that ϵ ϵ is most commonly used in analysis as an arbitrarily small (but positive) value
- How do you determine what $\\epsilon$ to use? - Mathematics Stack Exchange
When it comes to epsilon-delta proofs, almost all texts (if not all) appear to make a perfect choice of epsilon to begin with, such that when they work everything out we finally get say $$|f(x)-f(x
- Computing a limit using the $\\epsilon$-$\\delta$ definition.
I would like to resolve a paradox I'm arriving at when I want to use the $\\epsilon$-$\\delta$ definition of limits to actually compute limits I learned a theorem in Apostol's Mathematical Analysis
