    Be careful. Even if the powers of the numerator don't equal the denominator, there could still be a HA (the denom) has a larger power than the numerator (y=0). I think you misspoke.

    Guys I think one should also consult a textbook before or after watching a video. Patrick here made a huge mistake saying "horizontal asymptote exists only when the degree of the numerator is equal to the degree of the denominator, whereas horizontal asymptote exists when the degree of the numerator is is LESS THAN or EQUAL TO that of the denominator... but we all make mistakes, he was mistaken there.

    Thank you so much. You are a great savior, and a great person for taking your'e every day time to video tape this videos. It took me less than 5 second for everything to make sense. Yesterday in school i was in so much pain for not being able to answer the questions asked to me . Now i now what vertical, horizontal, and obliqe asymptotes are. Now let's see how i go in my test tomorrow. I will post my grade here hope i pass. Again thank you have a nice day.

    When the degree of the denominator is greater than that of the nominator, there exists horizontal asymptote which is y=0. Right?

  • @howardbaxter2514
    @howardbaxter2514 10 ปีที่แล้ว

    There is a horizontal asymptote if the denominator has a higher degree than the numerator. And you can only have a linear slant/ oblique asymptote if the numerator has one degree higher than the denominator but you can still have a oblique asymptote if the numerator has a degree that is 2 or more degrees higher than the denominator. I am learning this in Pre-Cal right now.

      "And you can only have a linear slant/ oblique asymptote if the numerator has one degree higher than the denominator but you can still have a oblique asymptote if the numerator has a degree that is 2 or more degrees higher than the denominator."
      You've made 2 conflicting statements here. I believe that only the first is accurate (i.e. "you can only have a linear slant/ oblique asymptote if the numerator has one degree higher than the denominator").

    Does the "degree of a polynomial" still come into play when there's a constant in the numerator and some power of x in the denominator, i.e. 1/x?

    • @patrickjmt
      @patrickjmt  6 ปีที่แล้ว

      1/x is no longer a polynomial, but a rational function. However, if you look at the ratio of the degrees (numerator/denominator) you can still glean some info

    "Horizontal asymptotes only exist if the degree of the numerator is equal to the degree of the denominator." ... FALSE! They only exist if the degree of the numerator is less than or equal to the degree of the denominator. If the degree of the numerator is less than the degree of the denominator, the asymptote is always going to be y=0. Otherwise, it will be the ratio of the coefficients of the leading terms.

  • @phendformyself
    @phendformyself 10 ปีที่แล้ว

    Good video, but why didn't you use synthetic division? And can't there be horizontal asymptotes when the degree of the denominator is larger than the numerator?

    • @FritzyNB
      @FritzyNB 10 ปีที่แล้ว

      You can use either long division or synthetic, it is up to the person. However if you're dividing by a square you can't use synthetic. Also I believe if the degree of the numerator is less than the degree of the denominator then it can't have a horizontal asymptote.

    • @garywhite8274
      @garywhite8274 10 ปีที่แล้ว

      FritzyNB If the degree of the numerator is less than the degree of the denominator then the horizontal asymptote is y=0. Watch his "Shortcut to Find Horizontal Asymptotes of Rational Functions" video. I'm not sure why he states otherwise in this video.

    • @garywhite8274
      @garywhite8274 10 ปีที่แล้ว

      FritzyNB Also, this example is not dividing by a square but rather by x^1 + 3 so synthetic division is entirely appropriate here.

    how did you get the y? i know its the oblique asymptote thing, and i know how to do it, but is it the same as y-intercepts?

    • @DocHolidayKY99
      @DocHolidayKY99 8 ปีที่แล้ว

      In division of N/D or simply Long division , etc...
      You have to fill in the missing degrees respectively.
      If you have X^3 +1/X
      you fill in the Numerator respectively going down the Degrees of X.
      So X^3 + 0X^2 +0X +1
      Otherwise it will mess up your whole division.

    In his other video, "shortcut to find horizontal asymptotes of rational functions" he also says that if the degree of the denominator is greater than the degree of the numerator y=0 is the asymptote... if the degree of the numerator=the degree of the denominator, there is a horizontal asymptote at the ratio of the leading coefficients.

    Yeah, there are such things but the definition of an asymptote define them as straight lines so to call it an asymptote would be technically wrong. There can be a curve that acts LIKE an asymptote, if that makes any sense..
    But for simplicity's sake, there are curved "asymptotes".
