      Typically because of intent: when you are looking something up you have full intent to learn it. Even when you think you have intent in class, there is always a possibility that something is distracting you with so many variables in the classroom. By coming to this video you actively are focused on engaging in the content rather than someone saying "hey, you need to know this so pay attention." Intent is one of the top factors of success in anything.

    phenomenal video! but I have one question, my teacher shows set notation as {x|x€Rx>3} How does this vary from your concept?

      @hudson3559 8 лет назад

      I mean {x|x €R, x

      Hudman321 I was taught that this is the correct form.

    I know that set notation and algebraic notation is the same thing so what is the difference between the two if they are the same.

    How would you write the set notation of a notation going from negative infinity to infinity?

    • @TheFatherCharles
      @TheFatherCharles 8 лет назад

      I think it would be { x l -∞ ≤ x ≤ ∞ }

    • @monasarbaz1694
      @monasarbaz1694 7 лет назад

      I believe my teacher said it was something like {x|x f(x)Eℝ}. I remember taking notes in class, but I don't know where they are.

    I watched this ONCE and it all made sense, and in class my teacher explains it like five times and I still don't get it :))

    Can you do a video on set-builder notation and how to sketch a graph of a set notation???? or unless you already made one and i just couldn't find it on your page, could you send me the link??

    In the last given, can "U" ( union symbol) be used rather than the word "or" for the set notation? That's what I always do.

    • @aditijakkilinki9896
      @aditijakkilinki9896 6 лет назад

      Darci Fernandez no you can’t do that...at least my teachers took off points if you did that! You have to use “or” or “and”

    • @darcifernandez9256
      @darcifernandez9256 6 лет назад

    how? why is this the answer? this is so much easier to explain than the teacher said.
