    At 11:35, since x goes to infinity, I think that we have to consider both case: (1) x goes to positive infinity and (2) x goes to negative infinity. In case (1), the answer is 2 (positive 2), but in case (2) the answer is -2 (negative 2) . In this problem, the method divide both numerator and denominator by 1/x is not a good choice. Instead, divide both numerator and denominator by 1/abs(x) (abs(x): absolute value of x) would be more generally correct. In case (1), 1/abs(x) equals 1/x (positive 1/x) and in case (2), 1/abs(x) = 1/-x (negative 1/x).

    One short cut rule you didn't seem to cover was when the x value is greater in the numerator (ex: 3x^4-10/6x^2+20) the limit will be +/- infinity since the top is outgrowing the bottom.

    16:14 Why did he multiply the radical in the denominator by 1/x^2, but the rest of the denominator by 1/x? I'm guessing it's because in the end, you're taking the limits individually, but I don't get the rule

    • @mirana6157
      @mirana6157 6 месяцев назад

      "Inside a radicle, we need to multiply by 1/x^2" is what he says.
      Because the 1/x is going under the radicle, its supposed to turn into
      1/x^2.
      Hope this helps!

    • @plon5284
      @plon5284 2 года назад +13

      ok im a year late but it turns out to be 9 because to be able to multiply √(9x^2) by (1/x) to cancel out the highest exponent, you need to get into the radical. So what he did without explaining was he converted (1/x) into (1/√x^2) bc they're the same, so √(9x^2)/(1/x) = √(9x^2)/√(1/x^2) which makes it √9. -bored college student

    • @sophia_skip15letters
      @sophia_skip15letters 4 года назад +1

      I think he does it to show WHY the limit of (8/3x+4) is equal to zero. Since he was already explaining why the limit of (1/x) is always zero, he made both the numerator and denominator in terms of (1/x) to prove his point. So you don't need to do it if you already get how and why the limit of the function is equal to zero, but he does it to explain it more thoroughly.

    In 11:51 why are we multiplying by 1/x³ instead of 1/x since this question is bottom heavy?
    Does anyone know?

    When you multiplied 1/x with √9x^2 +, is it not suppose to be √9x+
