Section 15.3 of Swokowski
: Motion
Look under Section 14.4:

Section 15.4 of Swokowski
: Curvature
Improvements to Notes on 15.4:
On 15.4.13, since we assume t > 0, the expression for curvature can be
simplified to:
6 / [ t (9t^2 +
4)^(3/2)]
"Factoring" and canceling can help a
lot when normalizing a VVF, but it might not be as helpful when differentiating,
since you would need to use a product rule.
Check out "Nested Circles Problem": http://www.dansmath.com/
(Dan Bach's site has lots of great links.)
Section 15.5 of Swokowski
: Tangential and Normal Components of Acceleration (bonus)
(I'm mostly skipping this section, except for
curvature. I am assigning some homework problems, most of which are relevant to
curvature. The relevant curvature formula in this section is in my notes for
15.4. If you're curious about the rest of Section 15.5, check Section 14.4 of
the following:
http://www.grossmont.edu/jennyvandeneynden/archive/M281_links.htm)
Section 15.6 of Swokowski : Kepler's Laws (skip)
(The results are interesting, though. Read them.)
CHAPTER 16:
(FOR QUIZ 2, WE WILL COVER AN INTRO TO FUNCTIONS
OF SEVERAL VARIABLES.)
Section 16.1 of Swokowski
: Functions of Several Variables
Look under Sections 13.6 and 15.1:
http://www.grossmont.edu/jennyvandeneynden/archive/M281_links.htm
Section 16.2 of Swokowski
: Limits and Continuity (see Math 150, Chapter 2)

exist along all lines:
