omg, isn't it magic? can i apply it to the volume of 3D or nD?

[@saliheenafridi9116]

yes

[@oneinabillion654]

He talked about 3D programming using matrix. I really want to know more about it

[@guilhermegondin151]

Doing it just for the boundary turns it more simple to explain without lost in generality, good approach.

[@supershaye]

This is directly related to the Jacobian.

[@1mol831]

Jacobian coordinates proofs have been killing me for the past month because it has to be used in a project. As a middle school student, it had been troubling to recognize how I should differentiate a column vector by using the laplacian operator.

[@1mol831]

Can you give help?

[@oneinabillion654]

@@1mol831 I started linear algebra and multivariable calculus playlist 2 weeks ago. I'm stopped halfway at jacobian in multivariable calculus and came to gain some prerequisite knowledge in linear algebra. I'm almost done with it. I'll look into it.

this is what i am looking for. thx a lot.

18:57; very neat result

[@MismeretMonk]

Nice! I've got it now :)

This is why I hate Khan academy. 20 minutes without using a single actual value, so freaking dumb.
