Partial derivatives of vector fields

[@Killian5671]

To the staff of Khan Academy - I am a recent highschool graduate, I found out how wonderful of a resource you provide during my ACT prep class. I would like to thank you all for what y'all do. Though I am sure that I am shouting into the void, I would like to let y'all know that I appreciate the opportunity that Khan Academy gives me to keep up with my math skills in-between highschool and college. And I'm sure I'll continue to use Khan Academy through out college for studying and note taking. Please continue to provide the miracle that you provide.

​@@tttv687 I know might be some ironic meaning in your sentence but for those who are reading this and dont know, the person that is giving this class is Grant Sanderson and he has a channel called 3Blue1Brown that is known for incredible mathematical animations.

This is analogous to the complex functions differentiation, by why are the cauchy reiman equatuons not used here

[@oliverfife208]

It's so amazing to reminisce on when grant used to be at Kahn academy.
