Textbook: Multivariable Mathematics by Theodore Shifrin
Suggested: Calculus on Manifolds by Michael Spivak
Note:
Spivak is a more advanced and more condensed textbook. It is useful if
you plan to pursue graduate studies in mathematics or math-related
subjects.
We will cover most, if not all, of the following topics:
-- Linear algebra of Euclidean space;
-- Limits and continuity;
-- Derivatives and extrema;
-- Inverse and implicit function theorems;
It is unlikely that we will have time to cover integration, but for your own sake, it will give a more complete picture if you read the chapters on integration.
For
most of you, even though the topics sound familiar, the course will
feel significantly different from the previous calculus courses you
have taken.
Everything will be defined and proved with rigour.
