    patrick, you make calculus so easy it's stupid. Whenever I need practice problems when I feel unconfident, I just go to your videos and practice. I just wanna kiss you irl man, even tho i'm a guy. I'm gonna ask my parents to support you on patreon man i love you dawg no homo

    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!

  • @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!

  • @Elk9
    @Elk9 15 років тому +1

    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.
    Your videos are always valuable for those who seek mathematical knowledge.

  • @oestera85
    @oestera85 7 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?

  • @patrickjmt
    @patrickjmt  13 років тому +2

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

    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.

    Greetings!! Your videos have been so helpful and I was wondering if you could address the following problem:
    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

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!

  • @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.

  • @phonogtaphologist
    @phonogtaphologist 12 років тому

    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!!

  • @motivatedmind11
    @motivatedmind11 6 років тому +1

    So my calculus book by Stewart has the problem you go over at the 7 minute mark as #45 in 1.6. And it said the answer was DNE even though it was asking for the limit of 0 from the left exactly how you have it. Very odd! I knew it was negative infinity! Thanks for making me not feel crazy.

    • @patrickjmt
      @patrickjmt  6 років тому +2

      well, if the solution is either + or - infinity, you can say that the limit DNE since it does not exist as a finite number. it is correct to say DNE although i encouraged people to use + or - infinity since it is more descriptive as to what is actually happening.

  • @subramaniyanvg6367
    @subramaniyanvg6367 5 років тому

    In The Last Problem when we apply 1/x - 1/x it becomes 0/x bcz common denominator is x and 1 - 1 becomes 0. So we have to graph for 0/x instead of 1/x with lim x->0+ it will always result in zero for any x we plug in
    . Remaining things r correct.
