  • In this video I go through the proof that every Lipschitz function is uniformly continuous. I hope this video helps someone who is studying mathematical analysis/advanced calculus.

    I really needed a playlist with proofs like this, to practice being more through with my proofs in my first semester.

    Could you kindly upload more videos just like these? I always wanted to learn mathematical analysis on a graduate level. Measure theory in particular 😁. In any case - thank you!!!

    Thank you so much. I must say I don't understand anything not the function nor the proof and this is something related to me for sure, can I know what is going on here and what video should I watch to understand this function?

    Thank you for the very informative video! But what I don't quite understand is, how does one decide, that when M > 0, you choose delta as δ= ϵ/M?

  • @learngermanwithvanessa
    @learngermanwithvanessa 3 года назад

    M also has to be either bigger or equal to M, right?

  • @coreymonsta7505
    @coreymonsta7505 3 года назад +1

    Lip. condition is like here’s all the work for you in your epsilon delta proof done for you, and tells you recall you’ve got control over the size of |x - y| as always lol

  • @caziobay
    @caziobay Год назад

    I think M can be negative if x=y for all x,y in D (i.e. D is a singleton set), since then we will have |f(x)-f(y)| = |f(x) - f(x)| = 0 and M|x-y| = M|x-x| = 0 for all x,y in D. Therefore, |f(x)-f(y)| 0.

  • @S24W2
    @S24W2 3 года назад

    Thank you , but in assuming it is lipschitz is assumed, ok but how do you know that absolute value of x-y is less than delta?

      function such that |f(x)-f(y)|

    A function f : [a, b] → R is said to satisfy a Lipschitz condition with Lipschitz constant L on [a, b]
    if, for every x, y ∈ [a, b], we have |f (x) − f (y)| ≤ L|x − y|.
    a. Show that if f satisfies a Lipschitz condition with Lipschitz constant L on an interval [a, b], then
    f ∈ C[a, b].
    b. Show that if f has a derivative that is bounded on [a, b] by L, then f satisfies a Lipschitz condition
    with Lipschitz constant L on [a, b].
    c. Give an example of a function that is continuous on a closed interval but does not satisfy a
    Lipschitz condition on the interval.

    it's clear, it is clear, it is clear, why do u solve a clear problem ??? Actually, u repeated the clear thing :) same as books

    • @TheMathSorcerer
      @TheMathSorcerer  3 года назад +1

      hahaha yeah, eveyrone says it's clear, and, it actually is, but still, worth to show the details! You'd be surprised:D
