[melisantika]

I am very happy to see the vidoe Double integrals in polar coordinates; applications from you, hopefully the others also are happy for You

[Onepissite]

I am very happy to see the vidoe after you give this Double integrals in polar coordinates; applications.

[Ondelendo]

I Love The Video Double integrals in polar coordinates; applications It Can Increase My Knowledge

[bebeheuy]

Steady I Really Like This Video Double integrals in polar coordinates; applications

[willamricard]

Nice Video That You Share , So Very Nice Thanks You Double integrals in polar coordinates; applications.

[imegatrone]

I Really Like The Video Double integrals in polar coordinates; applications From Your

[anakmudajaman]

after i watched this video, my insight is very open because the video Double integrals in polar coordinates; applications is very good to give information

lol komme aus münchen

[OriakoPhi]

Petty arguments between an Aerospace Engineering graduate student at Caltech and an international olympiad participant at the level of Grade 4 playground insults. You would think that being educated mathematically/physically translates to higher level cognition when communicating with other people? Think again.

[xXSparky117Xx]

@OriakoPhi

I agree, it's really just an issue of ego, which everyone seems to gain too much of when going to college.

Once they lose their ego, they might actually learn something.

[coltsfancolts]

ty for explaning where r dr dtheta comes from lol forgot r * theta in radions = length of circle edge

[joeglimmix]

he looks like matthew borderick...

[x1x2x3ct]

@joeglimmix who the fuck is m.b.???

[joeglimmix]

@x1x2x3ct american actor....it should read broderick

[anarchris]

wow actually explaining where rdrd(theta) comes from.........

[amitk19]

we use a planimeter to find the center of mass of an irregular shape.

[amitk19]

centre of gravity or cg!

[WarringGod]

ive been getting really down not been able to do this stuff in my physics stuff thx man this lecturer is awesome.

[jainv0905]

Can any1 say how should i download video????

[WarringGod]

@jainv0905 there is a program on google called youtube downloader

[kjelle90]

@jainv0905 If you use Firefox, then there's an extension (addon) called Video Downloadhelper. That is better than YouTube Downloader and it allows you to download videos from a lot of different websites. If you have any further questions, then let me know.

[FredTheMightyFraud]

I'm really disappointed by all the arguing in the comments section though... I would have imagined the people watching these lectures to educated, respectful and science-focused rather than hateful. Knowledge and wisdom, curiosity and doubt, that is the very essence of the scientific spirit. I sincerely hope that both gentlemen will eventually come to understand that if one's interest and passion about the scientific ideal is sincere, one must listen with respect.

[FredTheMightyFraud]

@FredTheMightyFraud  *I meant to BE educated (my mistake...)

[FredTheMightyFraud]

Thanks to MIT and professor Auroux for those fantastic lectures,

[dorood]

I would personally go up and shake this man's hand after every lecture... he's that damn good

[savvasik21]

Prof Auroux is whack!!!!!!! Reminds me of my multivariable calculus teacher Dr. M Kappos. MIT is also whack but i'm jealous of all these students who go there cause they have money. Most of them are nothing compared to the students in my school in terms of intelligence...

[dfszinho02]

@savvasik21 jealous much? MIT is the number one technical college in the world, in otherwords they ARE smarter than the students in ur school. BTW no uni in greece is even in top 100 so quiet there

[savvasik21]

@dfszinho02 Yeah you tell me about smartness. The fact that MIT has more money and better teachers doesn't mean that the students are smarter. They are just rich faggots who are trained to show smart. Greeks are historically smart and don't judge our universities cause in MIT there are about 10 greek professors and many graduate students who came there from greek unis. I don't trust that top list. And i was in the mathematics olympiad so you can't be cleverer than me.

[dfszinho02]

@savvasik21 Have u ever heard of admissions? MIT admits only 10% of all applicants and 70% need financial aid, that aid being 35,000$/yr. So they're not RICH FAGGOTS like you claim. If greeks are so smart, how come greece is 400 billion in debt. As for being 'cleaverer'. I taught myself advanced mathimatics when i was 14 and scored a prefect 990 on the GRE for MAth. Right now i attend CALTECH for grad school in aerospace engineering.

[savvasik21]

@dfszinho02 You are really dumb if you match the smartness of the greeks with the debt that the government created. It is not greek people's fault. I have been accepted in the Imperial College of London but due to money problem i could not go. Anyway I study electrical engineering in NTUA (which has a HUGE amount of scientists all over the world) and have taught myself vector calculus before uni and C++ before uni. And its cleverer not cleaverer. Learn proper english.

[dfszinho02]

@savvasik21 Your hilarious attempt to "top" my achievements failed pretty hard. So i'm going to destroy your little response. 1- i didnt know that the government in greece weren't greeks 2-Imperial college is shit and if u are smart you would have gotten a scholarship.3- Greek schools are shit 4- ur english comprehension skills failed there because i was simply making fun of you. Even through youtube i can tell u speak like a huge fob. (look it up)

[savvasik21]

@dfszinho02 Wow! I'm devastated. Everything you say about scholarships and aids by universities is pure bullshit cause they support just a part of your education and none of your living there. So I cannot live in Boston even with the 35000$ granted by MIT for overseas students. Secondly what you know about greek history and governments is what you get by listening to the news propaganda and not reading an encyclopedia.

[savvasik21]

@dfszinho02 Furthermore say whatever you want about greek schools. You just prove that you know shit about academic education. Finally you have made my balls look like ballons so.... Whatever FAG!!

[Basigek]

@savvasik21 the lectures that are uploaded from MIT are pretty informing (and helpful) whether you think professors are idiots or not. And an advice , being arrogant is not a bad thing , being arrogant with nothing extraordinary to prove extraordinary claims gives other people a good reason to think that you are also an idiot.

@dfszinho02 you say you are both smart , but your conversation was not intellectual at all

have a nice day :)

[savvasik21]

@Basigek Ye. Whatever. You are intellectual. Happy now?

[melody84321]

@savvasik21 HAHA, I just had to comment. Its actually "more clever." YOU learn proper english. This argument is the funniest thing ive heard in a while.

[savvasik21]

@melody84321 I'm not supposed to learn proper english. YOU learn greek.

[melody84321]

@savvasik21 HAHA, I just had to comment. Its actually "more clever." YOU learn proper english. This argument is the funniest thing ive heard in a while.

[alquiora]

After the Indian accent, this guy all by himself stands at number 2!

[chichoos07]

what undergraduate year is this course?

[gustgr]

@chichoos07 Most likely it is the second semester of the first year.

[jae44]

Wow this guys awesome! I hate it when I have professors who don't know wtf they're doing!

[sac83429]

This guy is crystal clear when he lectures. Absolutely phenomenal. I would have loved to take this guy for all of my Math classes. It would have been amazing.

[oolongtea0922]

Professor just had a haircut

[aVerKePedo]

Ok, correct me if im wrong but, when he is calculating the area of a Quarter disc of radius one we could do (to make sure of our answer)

A = (pi*r^2)/4... A = pi/4... why does he say it is pi/8?

With the double integral should be the same... i think he should not integrate the function times r... it is just the double integral of r dr dø, with those same limits, and it results in pi/4. Can someone tell me what is going on? Because i would not dare say he is wrong =D

[Sergio965]

@aVerKePedo So the thing that's happening here is that he's not finding the area of a circle, he's finding the volume of a region above a surface that 'looks' like a circle. What he plots there is the base of the surface, which is where you get your bounds of integration from.

If he was finding the area of a circle, the double integral of r*dr*dø with those bounds would indeed be correct and would yield pi/4 because the formula for the circle would be sqrt(x^2+y^2) = r = 1.

[jpmorgan187]

way to go MIT for the high quality videos!

[HopeInFreedom]

Wow, brilliant explanation of Moment of Inertia, far better than I got in physics.

[Metzlerguy98]

agreed! Definitely going to help for college =)

[An1MuS]

Thanks a lot for this video, and by the way, for all the others as well. 5 Stars
