Multivariable Calculus on Khan Academy: Think calculus. Then think algebra II and working with two variables in a single equation. Now generalize and combine these two mathematical concepts, and you begin to see some of what Multivariable calculus entails, only now include multi dimensional thinking. Typical concepts or operations may include: limits and continuity, partial differentiation, multiple integration, scalar functions, and fundamental theorem of calculus in multiple dimensions.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Help a lot for me. Thanks!

God the effort you put in. Thanks a lot for that. You are changing the lives of millions of people by providing quality education for free. I scored well by watching your videos. I could not donate at this moment as I am a student. But I will definitely denote to your organization when I will start earning. Again thanks a lot for your effort.

I love your work so much. Can someone do me a favour please? Between 3:19 and 3:52 is shown a 3D image of a surface. Could you or someone else tell me please what is the function of this surface.

The comment section make me nt concentrating hahahaha

Lol it's only in 240 p xD

Nice sir

Thanks so much!

Too beautifully explained…

Always rocking.

After I seeing this video I remember the thought of Einstein, that is "if you can't explain it simply ,then you don't understand it well enough ",sir u explained in simple manner, thanks sir🙏👍

Best teaching i have ever seen

amazing explanation

that was an amazing explanation!!

Beast

6:50

Could a double integral also be described as the "mass" or something related to the mass of an object in 2-dimensions? Does this hold true for triple integrals as well? If so would the integrand be a density function?

Wow it was awesome video my whole confusion got cleared thanks Khan academy

Why answer is negative sometimes though it's a volume?

Please sir this videos also available in hindi

really you are the best

8:04 why do you say that width is gonna be dx? I dont really understand what you mean by that at this moment. Please explain it to me

not now.

the explanation was soooo good . thank you sir

Water always finds a way to flow , khan you are that water , bringing free education.

wow thanks ..!! it was really getting itchy with my brain uptil now.!! thanks again

just ultimate

Is the first integral(inside integral) like a ghost integral cos it can "vary"???

very understandable compared to the larson textbook

Basically volume of a solid rectangular = LHW=f(x,y)dxdy

Excelent explanation.

Why do we use ds in line integral and dx here for area of one sheet ds=small arc lenght of curve dx=small change in x

I almost cried when i saw how logically and beautifully everything is explained in this video.

thank you. I understood double integral now

you dont explain well because you yourself is confused

This just made so much sense…..
