    Someone please give a medal to Prof. Auroux. Genius indeed how he closed the lecture with Divergence...

    @shakesbeer00 The parabola doesn't matter in terms of bounds because we know it becomes the unit circle in the xy plane. The double integral cares only about the xy plane, and so that's all you need to know in order to set up the integral.

    18:09 why the range of r goes from 0 to 1? I think the definition of S in this problem needs further clarification. S should be a paraboloid of z = x^2 + y^2 between z=0 and z=1. It is a little confusing by justing saying "above the unit disk".

    Wait, did he ever account for vector N not being a unit vector? He never required that the N vector represented the area of the delta slanted plane did he?

    • @agingerrail123
      @agingerrail123 8 ปีที่แล้ว

      In the formula, N appears both on top and on the bottom it is not necessary for vector N to be a unit vector.

  • @abbasbookwala

    I did not understand the last step replacing dA by dxdy. The proof contained slanted plane with an angle alpha to only one axis and not a general slant in both directions. Does this proof apply when we are considering a general slant to both x and y ? Will dA=dS Cos theta still be applicable?

    • @nickkong5754
      @nickkong5754 2 ปีที่แล้ว

      Remember that dA is the shadow of dS, so dx and dy are the dimensions of dA.
