    The way you broke this down was much better than how I was taught. You explained it in a way I could understand, and now I feel confident in ace-ing my test tomorrow. I only got 46% on my first try, and luckily I have a chance at a retest tomorrow. 100% here I come!

    I learned at school that the limit of IxI existed only in right and left hand limit form. Thanks to your explanation, now I know the reason for it.

    You know, I used to think the educational system was in shambles up until college, where dedicated professors built up the intellectual integrity of the individual. BULLSHIT. I'm in college and PatrickJMT has succeeded where teachers who are paid handsomely have failed. And IT'S FREE. Thank you, you've saved me from failing my finals :)

    @TheMimi1984 dne means it does not exist as a finite number. infinity is more descriptive than to say dne.

  • @Gtownprincess16
    @Gtownprincess16 15 років тому

    oh my god! I think you just saved me for my calculus final on thursday....my professor is convinced we should have learned this in high school and would not explain how to solve an absolute value to me, even when i asked. My high school teacher must have been slacking because I've never seen this before!! THANK YOU!

    @vip0IR no, it does not mean that at all. it just depend on the functions

  • @patrickjmt
    @patrickjmt  13 років тому +1

    @iluvbigbootie i am not making it equal two different values, i am simply rewriting it as a piecewise function

  • @patchina
    @patchina 15 років тому

    I literally screamed when it hit me that the first example would equal "does not exist", when you began evaluting the limit from both sides.
    I didn't know math could make me do that.

  • @cgme9535
    @cgme9535 6 років тому +1

    Yes! I am literally doing, nearly, the exact problem (with limits), and couldn't remember if you could simplify that rational equal to |1|/1 or if you had to do something different. Thank you for making this!

  • @patrickjmt
    @patrickjmt  12 років тому +9

    if the left hand limit and right hand limit are not the same, the limit does not exist. a limit can not have two different values.

  • @Obscurbus
    @Obscurbus 10 років тому +3

    Thank you, I would't be able to make it through my online calc class without your tutorials.

  • @oestera85
    @oestera85 8 років тому +11

    For the last problem, the textbook (Stewart, Early Transcendentals, 7th edition) says limit does not exist. (problem nr 45, chapter 2.3 ). They say it doesn't exist, because the denominator cannot go to zero while the nominator does not. But when I graph it with wolfram, it does go to negative infinity. My math tutor says that it doesn't exist because the items in the bracket cancel out each other. Why is the inconsistency?

    Thank you very much for this free tutoring!!! Its a good refresher and slightly more descriptive than I learned in class. I always thought of the sign function for absolute values but never related 'x' as the function in the absolute value tern, this insight has helped immensely. Thank you and keep it up!!

    lim 2x-1/2x^3-x^2
    x->0.5^- (from the left)
    the book solves it by first solving l2x-1l setting it to 2x-1 > or equal to 0 and 2x-1

    • @vanh0ek
      @vanh0ek 9 років тому +3

      +Max Boucher you can just basically use this method to remove the absolute values first, then once you have no abs value "signs" in your function, follow the videos of limits approaching infinity step by step.

    Great Video as Always Thank You.
    At 6:00 how are we "allowed" to cancel (x-1)/(x-1) when the substition of 1 yields 0/0?

  • @aravinth97
    @aravinth97 8 років тому +2

    So, if I were to redo the second example - but instead of approaching zero from the left side, approaching it from the right side - would the limit not exist or be zero?

    • @natecooperjones
      @natecooperjones 8 років тому +3

      Approaching from the right side makes the equation (1/x - 1/x) which simplifies to 0. So, the limit of any number greater than 0 (including 0+) will just be 0.

  • @timrtz20
    @timrtz20 13 років тому

    Education needs reform, PatrickJMT and other youtube educators are proof that they can be more effective than having a kid sit in a class while someone is paid to teach half as much in twice the amount of time.
