Does anybody know a site where i can find many epsilon delta problems?

AI Thread Summary
The discussion centers on the challenges of mastering epsilon-delta proofs in calculus, particularly after a poor performance on a midterm exam. Participants express frustration over the difficulty of these concepts and seek resources for practice problems and solutions. Recommendations include utilizing calculus textbooks and specific online resources, such as a YouTube channel and a tutorial site, which provide valuable explanations and examples. There is an emphasis on the importance of understanding the underlying concepts visually and creatively, rather than relying solely on rote practice. A suggestion is made to explore the Schaum series for additional proof-based problems, highlighting that developing intuition and creativity is crucial for success in epsilon-delta proofs.

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 \epsilon - \delta proofs is that you can make them up yourself!

Take any function f:\mathbb{R}\to\mathbb{R} 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.
