Differentiability is a local linear approximation property with consequences beyond computation.
Return here after the core path is secure, and connect each abstraction to a concrete derivative example.
Collecting formal language without linking it to the local linear model it describes.

Why Include These Notes?
These pages are optional. They do not add new differentiation techniques to memorize. They show that the familiar rules are shadows of broader ideas: local linear approximation, intermediate-value behavior, composition of linear maps, and local solvability of equations. A first-time learner may read them for perspective and continue without completing the exercises.
