Go and Taste » ### [calculus]The example of ε-δ definition problem

In the last meal [calculus]The clarification of ε-δ definition, we knew the actual meaning of $latex \varepsilon -\delta$ definition. This time we are going to use it. In this dish, I will show you the basic problem in $latex \varepsilon -\delta$ definition. Hope to make you understand clearly!

I believe that you learned the simple concepts of limit, integral and differential when you met calculus for the first time. However, when we want to learn deeper, there is a strange thing called \(\varepsilon -\delta\) definition in the chapter 1. We might memorize this stuff but don’t understand clearly. This article will help you to clarify the concept about the definition. Preconcept function In short, function is a thing that you give something to it, and something else will
