Correction - Coverage of sections 1.4 and 1.5

[Robert Zellmer]

In one of the e-mails I sent about homework, book editions, etc.
I stated we aren't covering sections 1.4 and part of 1.5.  That
applied only to the 14th edition.  We are covering those sections
in all the other editions.  In the 14th edition this is material that
used to be found only in ch 5.  The put some of that material in
chapter 1 (section 1.4 and part of 1.5) and repeat it again in
ch 5.  I've made a correction on the Notes link of my class web
page as well.
