how did they come up with these
both the matrix, and the units, and the equation and the ratio

i can recall the functions but not how or why

Second this, don't count on your lecturers to explain matrices to you properly. They are often poor at communicating their use.

no i mean seriously though, why do you decide it's a 4*4 matrix not 1*2, and the equation is equal to the inverse... is this more like law or do you actually have like real diagram to support this idea? also why is it u,v, then n not n,v,u or something

4x4 is a convenient representation. It lets you do rotations and translations in a single matrix.

so U V N basically means translation and rotation?

so a 1*1 matrix will just represent either translation or rotation?
