Intro to Cauchy Sequences and Cauchy Criterion | Real Analysis
What are Cauchy sequences? We introduce the Cauchy criterion for sequences and discuss its importance. A sequence is Cauchy if and only if it converges. So Cauchy sequences are another way of characterizing convergence without involving the limit. A sequence being Cauchy roughly means that

Completeness In this video, I define the notion of a complete metric space and show that the real numbers are complete. This is a nice application of Cauchy sequences and has deep consequences in topology and analysis Cauchy sequences: https://youtu.be/ltdjB0XG0lc Check out my Sequences

Uniform Continuity and Cauchy In this video, I answer a really interesting question about continuous functions: If sn is a Cauchy sequence and f is a continuous function, then is f(sn) Cauchy as well? Surprisingly this has to do with uniform continuity. Watch this video to find out why!

Proving the Function f(z) = 3x + y + i(3y - x) is Entire using the Cauchy Riemann Equations
In this video I prove that a function is entire using the Cauchy Riemann Equations. An entire function is one that is analytic on the entire complex plane. I hope this video helps someone out there!

Calculus - Continuous functions
This video will describe how calculus defines a continuous function using limits. Some examples are used to find where a function is continuous, and where it is not continuous. Remember to check that the value at c and the limit as x approaches c exist, and agree. For more videos please

Cauchy Sequence In this video, I define one of the most important concepts in analysis: Cauchy sequences. Those are sequences which "crowd" together, without necessarily going to a limit. Later, we'll see what implications they have in analysis. Check out my Sequences Playlist: https://w
