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.

    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.

    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

  18. Nikhil More at |

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

  19. Sanjay Sahu at |

    Please sir this videos also available in hindi

  20. Boody at |

    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

  22. Darry Andrews at |

    not now.

    just ultimate

  27. srayes1001 at |

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

  28. Hanh Vo at |

    very understandable compared to the larson textbook
    Basically volume of a solid rectangular = LHW=f(x,y)dxdy

  29. Gabriel Mello at |

    Excelent explanation.

  30. Subarna Subedi at |

    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

  31. ankit yadav at |

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

  32. itachi Theonlylegend at |

    thank you. I understood double integral now

  33. cooking shooking at |

    you dont explain well because you yourself is confused
