Discussion Overview

The discussion revolves around finding resources for practicing epsilon-delta proofs in calculus, particularly for those struggling with the concept. Participants share various suggestions for websites, textbooks, and alternative methods to enhance understanding and practice.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses frustration with epsilon-delta proofs and seeks a website with numerous problems and solutions.
  • Another participant suggests that one can create their own epsilon-delta proofs using any continuous function, emphasizing the importance of understanding the concept.
  • A different participant recommends looking in calculus textbooks for problems instead of relying solely on websites.
  • Several participants endorse a specific tutorial website as a useful resource for understanding limits.
  • One participant mentions the Schaum series books as a source for proof-based calculus problems.
  • Another participant argues that practicing without understanding the underlying concepts may be ineffective, suggesting a more intuitive approach to learning epsilon-delta proofs.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best resource for practicing epsilon-delta proofs, with multiple suggestions and approaches presented. Some emphasize the importance of understanding the concept, while others focus on the need for practice problems.

Contextual Notes

Some participants highlight the need for a balance between practice and conceptual understanding, indicating that different methods may work for different learners. There is no single agreed-upon source for practice problems.

I'm sick of still not getting this. I bombed the epsilon delta part of my mid term. A site where it gives many problems on epsilon delta and solutions would be amazing.

The amazing thing about [itex]\epsilon - \delta[/itex] proofs is that you can make them up yourself!

Take any function [itex]f:\mathbb{R}\to\mathbb{R}[/itex] that you know is continuous. And prove the limit exists.

You know the limit from intuition, now prove that what you think is correct through the use of epsilons and deltas!

You do not need a site to find them. Look in any good Calculus 1\2 textbook. You will find plenty there. Also, if you need to get a good handle on doing these epsilon delta limits proofs, there is a YouTube channel, "bullcleo1".
 
I really like this guy's http://tutorial.math.lamar.edu/Classes/CalcI/DefnOfLimit.aspx" . Hope you find it useful. :smile:

Ditto. Whomever Paul is, I love him. That site is great.

Thanks. Read it over. But I'm really looking for a site with just A BUNCH of problems so i can get more practice on them. Would anybody know of such sites?
 
Try one of the Schaum series books, I remember using one that was probably called "mathematical analysis 2", it had a lot of proof-based calculus problems.
 
Practicing will be useless if it doesn't help you understand the concept. Understand the concept visually and in other ways (like a game where I give you epsilon and challenge you to find delta). Then, practice. There's no general procedure that will always work. You just have to have some intuition and creativity.
