Why nth order differential eq can be represented by a sisytem of n equations of the first order?
For the same reason as an n bit vector can be represented as a sum of n 1-bit elements. Every order in diff eq is a memory element.
derivative operator maps (k+1)-dimensional vector into k-dimensional space
. That is why inverse requires one boundary condition to resolve uncertainty.
