    I think there’s something I don’t get about limit points. In the beginning everything was clear but approaching the end everything looked blurr. I don’t know what I don’t understand but I know there’s something I’m not getting with the concept of limit points

    So for a number to be a limit point it shouldnt necessarily be part of the interval. Right?

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  5 месяцев назад

      Yes, it should not necessarily be in the set. Limit point, basically indicates where the set or sequence is approaching.

    Is the deleted delta neighbourhood or the delta neighbourhood

      @@SkanCityAcademy_SirJohn I'm saying it's rather the deleted delta neighbourhood not the neighbourhood per say.

      @@SkanCityAcademy_SirJohn and that's the corollary to the bolzano wierstrass theorem. That if an infinite set is bounded that there at least a limit point. Which can be found by considering the deleted delta neighbourhood of the point in claim as a limit point if the open interval contains members of the set

    Without any given value for delta, how did you know that there would be infinitely many solutions between 0 and delta

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  5 месяцев назад +1

      The answer is right at the onset.
      The theorem specifies that delta should be greater than zero. So delta can be 0.1, 0.2, 0.3 etc
      So assuming delta is 0.1.
      Then we want to say that the intersection of S and (a-0.1, a+0.1) contains infinitely many points.
      Between a and a+0.1 which is the region of intersection, we can have for example,
      a + 0.001
      a + 0.002
      .
      .
      .
      .
      .
      And on and on

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  2 года назад +2

      kindly take notice of the fact that some infinite sets are bounded, others are not. In addition to that you should know that every bounded infinite set has at least a limit point.
