    Thankyou, so much for such a good explanation
    i was not able to understand this integration technique through any video on you tube except your video.You made this concept crystal clear for me.

    Why do we need to integrate using the jacobian coordinates? It seems more complex than cylindrical coordinates!

    • @andrewbulawa3273
      @andrewbulawa3273  Год назад +3

      It's the same thing! You use the Jacobian whenever you change coordinates. When we switch from Euclidean coordinates to polar or cylindrical coordinates, dxdy changes to r drdθ. The r in front of drdθ comes from the Jacobian. You may not have been told that when you first learned it, but that's what it is.

      @@andrewbulawa3273 Oh I get it now! So I can use any of these methods to find a volume of the solid including polar coordinates?

    btw anyone noticed that small hair on the paper?! lol

  • @HashemAljifri515

    If the determinant was negative, should I make it positive when evaluating double integral?, cuz i have a homework that contains two answers with the same boundaries but the determinant is negative

    • @hassanawad2131
      @hassanawad2131 Год назад +6

      The rule implies that you put the determinant in absolute value

    Isn't the primitive of 0 a constant ?

    • @andrewbulawa3273
      @andrewbulawa3273  6 месяцев назад +1

      Indeed it is. But then when you evaluate the constant function, say f(v) = c, at -5 and -9 and subtract, you get f(-5)-f(-9) = c - c = 0.

    Lol, there "u" are. Classic. Too bad you weren't using "r" as one of the variables.

  • @Artaxerxes.
    @Artaxerxes. 2 года назад +6

    Shouldn't the Jacobian be the transpose of what you wrote. Doesn't make a difference when calculating det though. Maybe I'm mistaken

    • @hikarifathan5143
      @hikarifathan5143 Год назад +3

      I'm thinking the same too

    • @andrewbulawa3273
      @andrewbulawa3273  Год назад +5

      Yes. You are correct. ..and what I was calling the Jacobian, I should have called the Jacobian Determinant.

    The determinant would be -1/2. You forgot you write the negative sign. But thank you for your great explanation

    • @Nyaterikk
      @Nyaterikk 6 месяцев назад +4

      he took the absolute value of the determinant

  • @MrJohanh80

    So the area of the parallelogram is equal to 0? 😮

    • @danieljorgeescobari6532
      @danieljorgeescobari6532 Год назад +2

      The x-y plane crosses the region R in a way that the positive volume is the same es the negative...add them and you get 0

    • @andrewbulawa3273
      @andrewbulawa3273  Год назад +5

      We're not computing area here. To compute area of a region, we would integrate the function f(x,y)=1. Here the function is f(x,y)=x-y, which gives something else.
