3d vector fields, introduction | Multivariable calculus | Khan Academy

Great! I can begin to imagine the practical applications!

Marvellous💯

WoW!

ありがとう😍

Sounds like 3blue 1brown guy

I'm on video 9 and haven't seen an ad yet!

Can you help please
How classification of critical points of system in three equation in 3d

How do you do this animations? What program do you use please?

This does not sound like the normal Khan academy guy I'm used to hearing hmmmmmmm

this series is fantastic. so much intuition of multivariable calc is lost simply because it's difficult to conceptualize. these videos are a godsend

You are amazing Grant. Love you

When you draw vector field in 3 dimensions f(1,0,0) it look like a cube. But these all cubes are not in 1 dimensions how?

thank you!

Which software do they use?, Anybody?

everyone definitely screamed like a koala when they heared the soothing voices of grant. 3b1b fam <3

Can someone explain what he means by the vectors don’t change when you move in x and z but change with y? I get mathematically why, but not sure conceptually why.

@4.25 when f(x,y,z) = [x y z] shouldnt the length of the vectors be zero since the starting and ending is the same point. how are they all pointing outwards. can someone explain pls?
