This is a collection of notes on calculus.
Sections marked with ``[NC]'' in their title are not part of the material covered in ``Analysis in Mechanical Engineering.'' Read them if you are interested.
The usual “Why this book?” blah-blah will eventually be found in a note at the back of this book, {N.1} A version history is in note {N.2}.
This is a living document. At this stage it is a rough initial concept. That is reflected in the version number. Maybe at some later time it becomes something useful for a general audience to read.
