Thank you sir. It's 6 AM and I've been studying all night for a test. :/ Got stuck on this.

comparing to the craziness of the last chapter which was about vectors in 3 dimensions, this chapter is cake.
It was insanely brain consuming to try to understand the last chapter intuitively to a point that it was a chore to study those sessions even though you explained them pretty well, I had to look up some terms on google, and youtube just to understand what the questions were asking at the first place, but thank to you, I have a much better grasp of it.
Overall Vectors comparing to just regular lines in a 3 dimensional space comparing to 2 dimensional, is a big jump.

What if the order was 4 or 5 should we write 4 or 5 subscript x's ? f_xxxx ? it's not neat.

what does it mean if the partial derivitive symbol or d has a suoerscript but its on its own in a term like (d^x) multiplied by the identity matrix
