    The real analysis playlist has a long ways to go, but I'm working on it! czcams.com/play/PLztBpqftvzxWo4HxUYV58ENhxHV32Wxli.html

      Absolutely! I pretty much skipped over a typical first chapter in analysis in my playlist, but I'll come back to it eventually to really set the stage for all the material. And NIP is a cool part of that!

      I think you may also like the Calculus playlist on my channel, specifically, I would recommend that you check the video from my channel called:
      "Visual Proof of The Heine-Borel Theorem and Compactness of [a,b]"
      I make very rigorous visual proof from calculus in this playlist. I also made a video about this theorem called :
      Cantor's Lemma Proof and Visualization

    Question, how does this prove that the real no. Line has no holes? If x belongs to the closed interval [a_n,b_n], then that could imply that x CAN be equal to a_n or b_n, thereby producing a hole between a_n and b_n?

    Hey WoM,any case where that x can be a set (finite), I cant find such Example and my stupid brain is getting more inclined towards a singleton set

  • @gonzajuarez4918
    @gonzajuarez4918 Před 10 měsíci +1

    Hey. Thanks for the video. I've been stuck at this for a couple of hours. One question though. Why doesn't this proof consider the case where one of the nested intervals is the empty set. My best guess is that this has to do with it being about an *infinite* sequence of closed nested sets. But again, the empty set is included in itself so it could go on and on and on and... on.
    If the empty set is considered in the sequence, then such x wouldn't exist. As per my understanding.

    • @Nikkikkikkiz

      a_n\leq x\leq b_n means that it has to be at least the single point x

    • @siriuss_
      @siriuss_ Před 3 měsíci +1

      We are dealing with real numbera here, consider a set [-1,1], then it contains [-1/2,1/2] and so on. Whats up with the empty one? here subsets of Reals are infinite, if it gets finite you get that that finite as your answer. Say, if empty set is contained here, the answer is empty, but it should be NESTED

    nice video, thx for upload this... may I ask...how to create the nested set so the intersection is (-2,1]

  • @okikiolaotitoloju2208

    Could we have used an infimum instead of a supremum for x?
