@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?
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?

Am I the only one to feel that cameraman is obsessed with zooming in things? That's really annoying - I am more confident in his camera('s resolution w/o zooming) than he is...
20:00 "There are many paraboloids in life" ~Auroux
Someone please give a medal to Prof. Auroux. Genius indeed how he closed the lecture with Divergence...
I love when he erases the blackboard.
Man, I miss calculus! So good to see these lectures!

Why can't Cornell professors be this good?
The best math teacher
Do maths/science/engineering students take this class or some other multivariable calculus course like 18.024?
In India engineers/physics students take a course like this and maths studenst atke 18.024
@@cantfindagoodchannelname7359 Which institute bro?
yeah this guy is great!
great stuff...
regards from australia!
Thanks for the proof of nds = dxdy

exactly
He means the part of paraboloid which is Above the disk on the xy plane
Great lecture. Thanks for uploading.
Splendid lecture.
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?
In the formula, N appears both on top and on the bottom it is not necessary for vector N to be a unit vector.

Remember that dA is the shadow of dS, so dx and dy are the dimensions of dA.
I Really Like The Video Divergence theorem. From Your
my lecturer covered this topic within 10 powerpoint slides-.-
This is helpful ❤️🤍
@shakesbeer00 Because it's over the unit circle.
One person disliked this video because he realized once 3d flux was explained excellently he still didn't understand it
Thanks ❤
MIT plz provides lecture of real analysis...
He is vector analysis lecturer. He can't teach other subject.

Isn't this theorem called after Ostrogradsky, since he is the first one to prove it?
yeah but pronunciation issues rose, so they changed it to divergence theorem, instead of ostorgradagsaskgsy
Antonij Mijoski why the fuck u care this man?? Jesus fcking christ, are u disrespecting Sir John Denis Auroux????
@hmpcon you have kassabov?

+Danny Bear Maybe his dream was to be a proffesional cameraman and he just loves to zoom in stuff dramatically (31:01)
When you clear black board sir awesome
32:22 :D
I loled so hard :'D
lol @ 32:20 and the class reaction...
Nice
Mmore Olympic erasing by Denis Auroux!!
32:28 I think he missed...
After 25 minute lecture I not understand what you have done,please sir explain it
He teach me how to draw
sorry to disappoint you but it's d(sigma) not dS. that MIT guy needs a reanimation.
This guy needs to take an English course.
imagine thinking having an accent means you don't know the language
Four years late but as a native English speaker, he speaks flawless English
@@atehortuajf yeah, common misconception of people who only know 1 language, pathetic monolinguals...
Please @mitopencourseware. Please label each video with the content covered in the video! I'm begging you!
