    Thank you for making this great material. You are easy to follow and to the point. Your comments about proof strategies, example vs non-examples, complex proof immediately followed by reminding us of the simple definition make these concepts easy to grasp. Beyond math, you have a great ability to teach. The M.I.T. students are lucky to have you as a professor.
    M.I.T., thank you for supporting open and free lectures.

    The tracking camera is quite awful it makes the blackboard unreadable sad

    Thank you for the series. Self-studying analysis (as many attempt) is difficult, but these videos offer a great supplement to reinforce ideas :)

    is there a person behind the camera, the track is quite awful

    a weird question but can we prove sequence xn is unbounded by introducing algorithm in it and then using Archimedean property

    There is a mistake in lecture notes, example 71. Example in the lecture notes picks epsilon_0=1/2 and then proceeds with 1=|(-1)^M-(-1)^(M+1)|. This is wrong. Epsilon should be 1; and the expression with absolute values evaluates to 2. The lecture video is correct, the lecture notes are not.

      Both work I believe. Of course, the absolute value does equate to 2 but >=1 is just a looser ineqn

    how is a monotonic sequence like 1,1,1,1,1..... which is bounded convergent?

      it converges to 1, you can verify this using hte definition of convergence

    how is x sub n -x =1

      @seancates8880 Рік тому

      I was wondering the same thing but what matters is that by hypothesis |x_n - x | < 1 so the argument still holds because B then can only be even bigger

    and also 1+1-c is a mistake I think
