    Just wanted to let you know you're a life saver, I was at the brink of thinking I might have to quit math until I discovered your videos and started understanding so much that went over my head from my lectures

    Having looked at various resources to get Cauchy sequences clear in my head, this is the first one I've truly understood. Thank you so much! Your explanation is super-clear.

    Your videos are just brilliant every time. Honestly gives me so much hope every time I feel like I wanna quit Math, because it proves to myself that I actually can understand these theorems. Thank you man.

      I hope they will be! Good luck and let me know if you ever have any questions! I don't know what text you'll be using, but my playlist mostly follows Real Analysis by Jay Cummings and Understanding Analysis by Abbott, though the playlist is still far from complete.

    Wow, I was just taken for a ride.. a wild ride. But thank heavens I did, that was amazing. I'm taking mathematical analysis and it's been tough for me to understand, kinda feeling like I shouldn't be there. We aren't onto this topic at the moment but on uniform continuity. You broke that down so well, that I now feel empowered because I understood all your steps. It was clear, well-structured and beautiful. Thank you so much for this wonderful piece. Take care.

    04:35 the information is not true. " In every metric space, each convergent sequence is a Cauchy sequence.
    The converse is not true in general."

    You are amazing. Please keep doing what you do. You make the language of math as easy as the ABC song.
    Is there any reason you used 2/ep.... or can one just choose any epsilon?
    I see now...Thanks again

    at 6:20, why is m,n > 21 not m,n => 21?

  • @KurdaHussein
    @KurdaHussein 2 года назад

    every converge is cauchy but not conversely.
    ex: 1/n on R-{0}

  • @krishnabahetra4641

    12:32, this is not correct to say that after applying the triangle inequality, it is not necessary for it to be less than epsilon.

      It was just chosen arbitrarily to show that the Cauchy inequality holds.
