Epsilon Delta Continuity (Example 6): 1/x
In this video, I use the epsilon-delta definition of continuity to show that f(x) = 1/x is continuous. This is a must-see for every calculus lover, enjoy! Continuity Playlist: https://www.youtube.com/playlist?list=PLJb1qAQIrmmB86yhDeAUZPY0dktFtb8Tj Subscribe to my channel: https://youtube

Here I show that the ratio of two continuous functions is continuous. I do it both by using epsilon-delta and the sequence definition of continuity. Interestingly, the proof is similar to the proof of the quotient rule for derivatives. Enjoy! Reciprocals of limits: https://youtu.be/eRs84C

What is a continuous extension?
Continuous Extension In this video, I define the concept of a continuous extension of a function and show that a function has a continuous extension if and only if it is uniformly continuous. This explains yet again why uniform continuity is so awesome Uniform Continuity: https://youtu.b

In this video I give a very straightforward proof that the sum f+g of continuous functions is continuous, both with the epsilon-delta definition and the sequence definition. I also show that any scalar multiple kf of a continuous function is continous. This implies that the set of continuo

In this video, I show a really neat result, namely that the maximum of two continuous functions is continuous. Enjoy the epsilon-delta extravaganza! Continuity Playlist: https://www.youtube.com/playlist?list=PLJb1qAQIrmmB86yhDeAUZPY0dktFtb8Tj Subscribe to my channel: https://youtube.com/d

In this video, I discuss what it means for a function in Rn to be continuous, and more generally about continuity in metric spaces. Moreover, I show that a function is continuous if and only if each component is continuous. Enjoy the metric space extravaganza! Every function is continuous

David Meyer (1/30/18): Some algebraic stability theorems for generalized persistence modules
From an algebraic point of view, generalized persistence modules can be interpreted as finitely-generated modules for a poset algebra. We prove an algebraic analogue of the isometry theorem of Bauer and Lesnick for a large class of posets. This theorem shows that for such posets, the int

Zorn's Lemma, The Well-Ordering Theorem, and Undefinability (Version 2.0)
Zorn's Lemma and The Well-ordering Theorem are seemingly straightforward statements, but they give incredibly mind-bending results. Orderings, Hasse Diagrams, and the Ordinals / set theory will come up in this video as tools to get a better view of where the "proof" of Zorn's lemma comes f

Pre-Calculus - Where is a function continuous
This video covers how you can tell if a function is continuous or not using an informal definition for continuity. Later in the video, we look at a function that is not continuous for all values, but is continuous for certain intervals. For more videos visit http://www.mysecretmathtutor.
