Thank you sir

[@bhumikagupta1978]

Thanks a lot :) i was stuck here since so long

[@ramanathanseranthian3210]

can someone explain to me why df does not equal to the gradient dot d(theta)? As f also varies with theta!

[@harrisonbennett7122]

Very clear! A big thank you from a mathematics undergrad.

[@tomaskovarik1]

can someone explain to me why df equals the gradient dot dr? That makes no sense

[@filipposkalofotias662]

Check gradient theorem, lecture 43.

[@SanadIqbalBME]

Thanks bro🔥

[@dedclan6459]

These videos are so clear i m watching them on 2x speed

[@fahimmumand]

A little explanation is needed on where do the r hat and theta come from?

[@sourish_mitra]

Thank you- it us really nice and helpful to me

[@arvind3656]

Nice video 👍

[@palantea1367]

thank you! keep making videos please (:

using vectors i and j without explanation?

[@ProfJeffreyChasnov]

Lecture 26 in a course, lol.

[@kingsgambit]

I was also scratching my head, he explains it in an early video apparently. Its just the unit vectors in the x and y direction. Hope that helps

@@ProfJeffreyChasnov there are a million different conventions on how to name units vectors, coordinates etc. -- it's not as apparent to anyone as you think, so its nice to just explain it if anyone asks. Thanks for your helpful video.
