wheres the link...



[melisantika]

I am very happy to see the vidoe Introduction to partial derivatives. from you, hopefully the others also are happy for You

[Onepissite]

I am very happy to see the vidoe after you give this Introduction to partial derivatives

[Ondelendo]

I Love The Video Introduction to partial derivatives It Can Increase My Knowledge

[bebeheuy]

Steady I Really Like This Video Introduction to partial derivatives.

[willamricard]

Nice Video Introduction to partial derivatives That You Share , So Very Nice Thanks You

[imegatrone]

I Really Like The Video From Your Introduction to partial derivatives.

[anakmudajaman]

after i watched this video, my insight is very open because the video is very good to give information Introduction to partial derivatives

[DrunkWhiteGuy]

Your students must like so much to have you as a teacher.

[Mikmacer]

amazing explanation, thanks for doing this !

[teejmd91]

let's get into the meat and potatoes

[Marcinkonys]

This is big help. Thanks!

[WontonSandwich]

11:11 !!!

[osx101]

like it for subtitle.

[ny1fanta]

we should all donate money khan so he can buy the fastest computer in the world, he deserves it!

[olliesjollies68]

"whats the derisive of 2x with respect to x, well its just 2x" umm actually its should be "whats they derisive of x squared with respect to x, well its 2x

[Arrow9100kj]

Great video as usual Mr.Khan! Don't forget to leave the link for the plotting freeware =D!

[Killer9117]

Thank you Based Khan. *cries*

[luvsingin6]

yum, meat and potatoes

[zeeshan3dge]

i like your "I don't know"

[RatherBeWatchingPorn]

There would be more likes if the button had the right-hand rule hand on it :)

[xKMHxI2EAP3Rx]

I wish I knew about your videos while I was in school :/

[jea1080]

i love meat and potatoes

[rotflmaopmpqxyz]

Is there a such thing as a tangent surface? like a plane that touches the one point you're looking for?

[simanbrar]

hello dear sir, Could you tell me which sofware are you working to draw all these things.

thankyou

[wolterh6]

hey @khanacademy did you post the link to the plotting app?

[Shaneyyy23]

love it.

[0871356005]

my maths lecture said your voice is the voice of a person that you would love to hug.

[AndrewEG]

Sal your a fantastic teacher! thank you so much you helped me get into Mechanical Engineering!

[a1malik]

Salman Bhai ap konsa software use kar rahe hain graphing kay liye?

[abruptcall]

I was very impressed by your video. Thanks.^^

[speeron]

there is a mistake at 8:23. the transcript says "what's the derivative of 2x with respect to x? well it's just 2x".

[1073601]

i'm sorry, but is this multi-variable calculus?

all your calculus videos are bunched together and i can't tell where o n the playlist your multi-variable calc videos start

[cram2481]

2:51 "...But let's get to the meat and potatoes".

[qrrak]

thank you for your fantastic job Salman Khan. God bless you.

[mcavalera4]

i have been studying partial derivatives today and I really didn't visualise them that much as I did with this video...Great work man...Keep up the great work !!!

[xlthenoob]

now it sounds ridiculous that I'm paying over $500 for a multivariable calculus course over these videos

of course credit aren't given for watching these, but it's more seemly that universities are charging us fees for more non-trivial reasons

[nguyentuan1990]

are you a teacher? you are aewsome, im having problem with cal3 and this is going to give me another A on the next test.

[KingOfShadows92]

I learned more from your video than I did from an hour of my prof teaching... wish I had you as my prof!

[DzSchuur]

Thank you very much for this video!!

[qstong]

nice saved me a great deal of time reading textbook!

[jlmknight]

thanks for the help y cant they teach like this in university?

[TheTanman1234543]

Alg. 2. Im probably never gonna get this far in math

[1073601]

@TheTanman1234543  it's all baby steps

you'll get there eventually

[gregorioosorio16687]

Hello! Somebody know either software for make math graphics for my seminario, please if it 's free or open source, etc even better!!!! Thanks a lot!

[GlowStringTheory]

@gregorioosorio16687 in one of his later videos he drags the app far enough into the window that i could see the programs name. its called javaview. google magic! :D

[Soymilllk]

So good! i've been doing partial derivatives all semester and having NO CLUE what they actually ment. This video has finally given me a visual understand of what a partial derivative actually is!

thank you so much sal!!!!!!!!!! i love u

[itsmancini]

haha " so I don't sound like I'm melting"....

[100nassar]

Hi Sal,

You mentioned giving the link the the 3D plot program you used here.

If you have, where can I find it...Really need this, but can't seem to find it on my own.

Thanks

--dale nassar

[jorgandar]

wow..i finally understand partial derivatives! :D

[caoutchoucmilisec]

the name of the free plotting software please? thank you for your effort

[ChenJunHung]

how do i put a translation on the video?

[Procrastinatathor]

You mean kinda closed captioning? Go check out "Youtube

Subtitler", it's an online page to help you sub or add subs you already have on your PC to a video. I tried subbing on of Khan's video but it's not exactly easy nor short to do...

[asdfqwerty2000]

The right-hand rule is the gang sign of mathematicians.

[skyfaze]

@asdfqwerty2000 and physcists for magnetic force

[SolidSnyder]

@skyfaze hullz yeah, dog. Maxwell would be proud

[rythmgangsta]

Keep these videos comming...you are much more interesting than my boring lectureres..helping me a lot !!

Thanks !! :)

[fermixx]

really cool ! the graphic made it way easier to understand.

going into 3d is a whole other thing, and my book doesnt seem to like putting some drawings..

[xenofon9]

Very nice video, you are explaining very very good, like really awsome, thanks i hope u make more!

[RMRockstar]

this video really clarified all misunderstanding of this subject....thanx!!!! i will be watching all your videos as part of my study methods from now on

[teamkilla]

lol nice hand :D

[benorge1]

Hey man! Just letting you know that I created a you-tube account just to thank you!!! I have my exam tomorrow and you just saved me around an hour of nutting it out myself :) Cheers from Australia mate

[libbern]

I have about this in a course (not calculus) where some professor have tried to explain it in a very badly written compendium. Of course, he believes that what he has written is better than any other books, but I dont understand shit of it as things arent explained. The formulas are just throwed in ones face while reading it:O

But now, thanks to Khan, I understand partial derivatives... Great guy. Thanks.

[hcipriano]

You are incredible. Hope that when I teach, I do as well as you. THANK YOU

[Bearkiller777]

what is the link to the java grapher you are using? I am in a calc.3 course I would like to know. please send ASAP thanks great vids explain things really well.

[Mrelevatorman]

Wow! That was very well explained. Thank you!

[thelemur]

help on rememberring right hand rule: remember that the thumb is "k", by the "ok" gesture, where u use "thumbs up".

remember the index finger as "pointing at someone, while saying "I disagree on...:" and make som sort of picture in ur mind of that instance... And be crative, and remember the middle finger, by some other gesture, and link it with the letter "J", maybe a name or something... :)

[Seksivince]

This rocks, helped me brush up in no time.

[VeryFatFishh]

thank you !

[99spinz]

good job, you even have the voice for it..

[blleeed]

omg thnx alot!!

[kristoferson16]

awesome job man, you jus made that soo simple for me ; )

[ASeeling]

This video was amazing.

Thanks!

[sonic41592]

Hey, can you please make a video explaining how to find the equation for a tangent plain at a point on a surface?

[lliasa79]

very good way to explain

[1luvinCreation]

thanx dude

[cressilia]

Hey, AMAZING VIDEO!

What is the link?

I don't get 3D graphing. While x=2, y can equal 3,2,4,5,6,7,1, or 1,392,835,543.943/8.r that means that the whole box will be filled.

[clevercleverchris]

ya its true that when x=2 y can equal anything, but that does not mean every point in the box satisfies the equation. You have to remember that when graphing in 3D, you have to take "z" into consideration as well. The whole box will not be filled, since only parts of it have coordinates that satisfy the original equation

[cressilia]

Yeah, as soon as I posted it, I figured it out. I felt dumb.

P.S.

Sorry for waiting two months to reply!

[McLarensupporter]

lol 5:18 , "look at that..." XD

[porkman385]

awesome! I'm in calc 1 and even I can understand this. I love your videos. I'm in calc AB, but because of your videos I'm going to take the BC exam. THANKS!

[anvilsalesman]

awesome! I did the same thing last year and got a five. Everything I learned came from these videos, and I just did a few practice problems the night before to make sure I got it. khan is awesome

[bomberfun1]

@porkman385 Calc AB isn't real Calculus. Neither is BC.

[gambuzo]

Was the graph f(x,y) = x2+y for sure? It seemed to me as f(x,y) = x2+y2.

Anyway, fantastic material, thank you !!!

[khanacademy]

You are right. I had graphed x2+y2 first and then typed in x2+y but forgot to refresh the graph.

[azzuwan78]

Excellent explainations!

[Xs1t0ry]

Great vid--thanks!

[anvilsalesman]

thanks for doing this, i had been meaning to learn more calc, but could never quite get over this

[gamemaster014]

cooool 3 dimensional =]]]]]]]
