coverage in Ch 15 up through today, revised homework listing

[Robert Zellmer]

Someone asked where we were in ch 15 when we ended today.
I've covered up through section 15.6.  They also asked about the
end-of-chapter problems and doing things one section at a time.

In a previous e-mail I addressed how first 4 sections are closely 
related and
the book combines all four sections into one section of homework. I stated
my homework link tells you which problems cover each section.  I've revised
how I list the problems.  Hopefully it will be a little easier to follow 
which problems
to do after you finish analyzing a section.
