Lec 30: Line integrals in space, curl, exactness... | MIT 18.02 Multivariable Calculus, Fall 2007

[@YeaTyrone]

this guy is an amazing lecturer. his videos have helped me out so much. i wish the camera man was a fraction as good as he is, though.

[@atehortuajf]

6 more lectures, 2 more psets, 1 more exam. We're almost there!

[@9888565407]

where can i get the exams? i only got the psets on ocw site

[@atehortuajf]

@@9888565407 ocw.mit.edu/courses/mathematics/18-02-multivariable-calculus-fall-2007/exams/ has practice exams. ocw.mit.edu/courses/mathematics/18-02sc-multivariable-calculus-fall-2010/3.-double-integrals-and-line-integrals-in-the-plane has more resources being designed for ocw and based on this one

I will miss these lectures so so much

[@cctang4922]

To check the vector field is conservative, compute the cul of the vector field and see if it is zero .I think it is easier.

[@kaushaltimilsina7727]

For the condition to be a vector field, that seems like the formulation that the curl of the gradient of f=0 , meaning that its direction does not change and hence is a scalar.

@MrAnuarsh the infinitesimal length of r (so small it has no length) is the vector coordinates of the infinitesimal length of x, infinitesimal length of y, and infinitesimal length of z

I am currently taking Heat transfer, His explanation broaden my knowledge. 'Multivariable Prof. wasn't of much of assistance'

The "c1+c2+c3" method is def better!

[@Vykke]

Imagine him speaking fluent english instead. He just trolled them all, all these lectures. Then goes home and laughs everytime

[@AnuarPhysics]

@afjkaf312 Ok, but mathematically, how can you define that? In Differential geometry, an expression like dx maybe means a 1-form. But the "vector" (dx,dy,dz) has no sense.

[@not_amanullah]

Thanks ❤🤍

[@andreas_gswerve]

jesus these kids spitted out their lungs

[@yonatanable]

This is guy is so good in computation than concept explanation

[@rosadovelascojosuedavid1894]

No

[@TonyG-n1m]

Huh?

[@raydredX]

I am very happy to why the fuck is this full of bots in space and curl. Thank you, it really helps

[@golfguy777]

@hesham3540 yes

[@ameerhamza4816]

Why is everyone coughing

[@godzillanismo4892]

Corona virus

[@pabloarroyo1023]

It’s late fall or early winter in Boston, so people are starting to get colds

[@BareClause]

my ffff do butiful

[@not_amanullah]

This is helpful ❤️🤍

[@joshie92]

"unapropriate" LOL

[@manoum1]

the coughing noise is freaking annoying!! but this video is awesome.
