Linear algebra (ex: multiply the matrices A and B), multivariable calculus (example: find ∇F with F=[xy,yz,xz]^T ), or actual "multidimensional analysis" (example: define the norm of [1m,1m/s,1m/s^2 ] in a way that makes sense)? I can help with all three.

Yeah Multivariable calculus is the thing. I keep forgetting the name.

Sounds like fun! I'm going to bed soonish but I'm willing to answer questions about multivariable calculus probably when I wake up.

When I took multivariable calculus, the two books that really helped me "get the picture" were Multivariable Calculus with Linear Algebra and Series by Trench and Kolman, and Calculus of Vector Functions by Williamson, Crowell, and Trotter. Both are on LibGen and both are cheap because they're old books. But their real strength lies in the fact that both books start with basic matrix algebra, and the interplay between calculus and linear algebra is stressed throughout, unlike a lot of the books I looked at (and frankly the class I took) which tried to hide the underlying linear algebra.

Thanks for the offer! The exam is tomorrow (today is another) so there isn't a lot of time to prepare anymore. I'll just be writing a page of notes that we can take to the exam as a cheat sheet. Still, if something comes up, I might just ask you.

Thanks for the offer.

Ouch. Been there. Good luck on your exams!

Thanks, I'll need it. Today went well at least, but now I need to prepare for math Tomorrow

Simply study the Stokes theorem (in this meme), basically all of MVC >.>

Good luck.
