    you know, that ad before all of these videos starts out with "tired of scrounging youtube for math help?" or something, and thanks to patricjmt, no, actually, i'm not. youtube is working just fine.

    you're a hero for this. my calc 3 professor never explains each step thoroughly and i was straight lost trying to understand how to find the boundaries. i wish more professors just took the time to go step by step instead of expecting us to pull the info from our asses lol

    OMG this dude is so awesome our teacher went over this stuff today! But he writes so fast no one can keep up and listen at the same time. I come youtube today and the first thing i see in the middle page is my subscriptions box. And what do i see? ASK ME, What do i see? I SEE MY MAN PATRICK (JMT) posting a video about absolute min/max. My man! This is why I tell everyone i talk to about math: "Ay you know Patrickjmt? Cus if you dont, you losing!"

    Patrick thank you so much for all your help! My friends and I all appreciate your videos, they are easy to follow and explain which steps to do in what order and why. I cannot thank you enough for all your help and I don't think I would have gotten an A in my math class without you :)

    Okay...Actually my midterm is tomorrow and now I am going to preview this chapter...But nice and clear video!
    I still have a question though, so what if you have a higher order function, say, f(x,y) = 4*x*y - x^4 _ 2*y^2 and I solve for the critical points and got y - x^3 = 0 & x -y =0. So do I have to always make y-x^3 = x -y and solve for x and y? (this process is super time consuming....) Do you have any other way? Thx!

    If only I had this when I was going through the Abs Max and Min.
    How about a video on Cylindrical Coordinates? I tried to find one earlier and it seems you dont have any (even though Its Polar Coordinates with z added in). Im sure others besides myself would appreciate it.

    What about the cases when your derivatives are a number like Fx=1 and Fy=1 for equation x+y+1=F(x,y) ? on set x^2+y^2

  • @AK-gt8zy
    @AK-gt8zy 8 лет назад

    Question: when the equation DNE at a point, that is also a critical point right? how would you find the point where the equation DNE?

    • @skateboarderlucc
      @skateboarderlucc 8 лет назад

      DNE is short for does not exist; I think youre looking for "undefined" ;)

  • @sakif7
    @sakif7 11 лет назад

    setting those partials equal to zero and getting values for (x,y) as critical points in this problem was super easy..
    unfortunately on my exams they much more complicated..
    is there any algebra videos that explain how to find critical points with much more complicated partials derivatives to set as zero ??

  • @shehesheha
    @shehesheha 11 лет назад

    And how do I find the critical points of an absolute value function, such as | 3t - 8 |?
