    I just realized Professor Leonard probably watches the whole video while editing it to point out any mistakes he might've made.That's a lot of work! He puts in a LOOOOT of effort into every single video. He stands and lectures for 2 hours straight. How many people can do that without collapsing? Honestly, teachers are so underappreciated and especially good ones like Professor Leonard deserve ALL the good things in life. I cannot be more grateful to him.

    But Prof. at 1:05:50 when I take the bigger one means
    2x²-5x+2/x²-4 = 2
    then I got x = 2,,there is no mathematical nonsensical statement produce,, I got the intersection point, but in the other hand the easy one produce a nonsensical statement,, that's contradicts and when I'm going to put x=2 in f(x), that's undefined, (2, undefined).
    Please help me

      Great question, but yes, you're not going to get the same answer if its not a cross. In this case you're getting x=2 back showing where (if at all) you're going to have a H.A. cross. But because you know there's a hole at x=2, you know that there wont be a cross at that point. Using the simplified version of the fraction is just a different road to get to the same conclusion. Its just in this case you're getting that "non-sense answer" where two different numbers equal each other. Again great question, because yes, first time trying it you're expecting to get the same answer for both the original function and the simplified version. Two different "roads" that lead to two different "destinations" but the end and final conclusions are consistent.

    @33:40 This became completely confusing to me. How did he identify there was a positive shaped quadratic asymptote? I didn't follow how he determined the (2,4) coordinates of it either. Further, do we treat parabolic shaped asymptotes as horizontal, or vertical asymptotes (important for crossing behaviour). Finally, I do not understand why the functional parabola is negative oriented, since the coefficient of the reduced rational leading terms are positive!

    1:05:40 P.leonard said that it doesn’t matter whether or not you use the main or simplified version of the function when calculating intersection of the horizontal asymptote, but when i used the main function, i got x=2, meaning that there is an intersection.
    2x^2-5x+2=2(x^2-4)
    2x^2-5x+2=2x^2-8
    -5x+2=-8
    -5x=-10, so x=2….. what’s happening here?

    Can someone help at 1:06:20. If I do it with the reduced fraction, I come out with no cross, but if I do it with the original function I get a cross at x=2. I do (2x^2 - 5x +2) = 2(x^2 - 4), I then factor to (2x^2 - 5x +2) = 2x^2 - 8, the 2x^2 cancels out, so end up with -5x + 2 = -8, this can factor to 5x = 10, which reduces to x = 2. I don't know where i made a mistake as I should expect it to not factor down right?

      hi joesph ..thanks for asking i ran with the same problem .. the ans to this question is that when you do with original function you get intersection at x=2 and later on we find that we have a hole at x=2 the hole tells that there is nothing at x=2 so it becomes non sense statement about what we found earlier(intersection at x=2) .....if we do that in the simplified function where the hole is already cancelled we do find that it becomes a non sensical statement i hope it helps

  • @rosepierce9382
    @rosepierce9382 Год назад

    In the last problem, wouldn't the horizontal and vertical asymptotes be also negative? The even vertical asymptote goes down and the odd vertical asymptote is reflected about the origin. But I guess in the end it doesn't matter because the negatives would cancel out anyway.
