E. Alec Johnson's Pedagogical notes for multivariable calculus
Appendices (not part of course material)
The above course notes are in the public domain.
(You can get the original tex files by using
the "copy link location" feature of your browser
and changing the file extension in the URL
from ".pdf" to ".tex".)
If you make substantial improvements I would
appreciate getting a copy.
Probably the greatest deficiency in these notes is
that they have no figures.
I ought to add discussion of the determinant and the notion of
oriented area and volume.
