    Bro why do teachers not teach like this. It actually pisses me off why they don’t teach so well and simple with patience. I’ve learned more in 7 minutes than my teacher did in a week

      Your teacher probably has poor public speaking skills, making it difficult to focus on what they're saying.

      not a lying story, our teacher is teaching this to us, and everytime we got the answer wrong, she always cuss at us sometimes, and calls us idiots many times, I don't rlly understand what she is saying, all of her examples are nonsense

    There could be an asymptote if m>n by just 1. That's slanted asymptote

    • @RadoHudran
      @RadoHudran 2 года назад +3

      Yup
      On my exam they literally gave me such a problem where m>n and I couldn't do it.

  • @geolescano4695
    @geolescano4695 4 года назад +3

    Correction sir on 3:49 you thought that when n > m then y = 0? and when m > n then y = NHA?
    But according to the books and some references it is not. The correct is:
    If n > m , then y = 0
    If n < m or m > n then y = No Horizontal Asymptote..

    Thank you so much for this tutorial. I am learning things I've never known before because I realize that there are so many things in life that I don't know about. The truth is, I'm learning Further Maths due to having some interest in mathematics and I wanted to know my true capabilities by learning things beyond what I'm supposed to cover because I'm only in year 9. I've done the same thing in some Oxford university maths lectures. I want to finish watching the ones on complex numbers and dynamics.

Once more, she told me to reach out to tutoring to teach me this stuff when it is due tuesday and they are only open on the monday. You are a lifesaver, thank you so much! This video has cut through brain-fog more effectively than the textbook and exercises posed by my college algebra class.

  • @club6525

    The definition for asymptotes is incorrect. Asymptotes are not lines since lines are real object. Rather, they are boundaries. Second, the function can touch and even cross asymptotes such as in the case of (x-1)/(x^2 - x - 6)

      @nandini2040 4 года назад +8

      there is! for the horizontal asymptote, our teacher told us to calculate the value of the limit of x approaching infinity for the function. if you've done limits, it's pretty easy to get it right. for the vertical one, check for points where the denominator is zero. this is because the vertical asymptote is defined as the finite value of x where y approaches + or - infinity. hope that helps!

    • @carultch
      @carultch 8 месяцев назад

      If the denominator has a higher degree, it will have vertical asymptotes at each pole, and horizontal asymptotes at y=0.
      If the two degrees are equal, it will also have a vertical asymptote at each pole, but its horizontal asymptotes will be shifted to a different vertical position.
      If the numerator is of a higher degree than the denominator, it will have oblique asymptotes instead of horizontal asymptotes. The vertical asymptotes will still oxxur at the poles.

    What about oblique asymptotes and holes?

    • @carultch
      @carultch 8 месяцев назад +1

      Oblique asymptotes are asymptotes that aren't parallel to either of the two coordinate axes, but instead approach a diagonal line.
      You'll see this for rational functions, when the numerator has a higher degree than the denominator.
      As an example, y = x^2/(x + 4) has a behavior, where in the long run, it approaches the line y = x - 1. This occurs both as x approaches infinity, and as x approaches -infinity.
