787.03 Summer 2003 Week 7
Week 7 (week of August 4). Topic for the week:
Differentiation (Chapter 1.4 in Berkeley Problems, chapter 2 in
Kaczor and Nowak V.2).
Next mock qualifying exam: Tuesday, August 12, 6:15 pm. I'll
try to reserve MA10.
On Monday, August 4, I reminded us of the homework assignment
for Friday (do the Spring 2002 qualifying exam, and Berekely
problem 2.4.27). Again try to do the old qualifying exam in a 3
hour block as if it was a real one. Then you can go back and
solve whatever you didn't get.
For other homework (not to hand in) I suggested we do problems in Berkeley,
chapter 1.4, and Kaczor and Nowak V.2, chapters 2.1 and 2.2.
In class we solved the following problems: Berkeley 1.4.26, 1.4.17,
1.4.18, and Kaczor and Nowak V.2, problem 2.1.12.
On Tuesday, August 5, we solved the following problems form
old qualifying exams related to differentiation: Autumn 95 #2,
Spring 95 #5, Autumn 00 #4, and Autumn 99 #5 (we stopped before
verifying an elementary but important detail-make sure you
check it!).
Here are solutions to problem set 4.
On Wednesday, August 6, we did problems 2.2.17, 2.2.20, 2.2.22 from
Kaczor and Nowak, V2, and Spring 92 #2.
On Friday, August 8, we solved problems 2.2.28 (in two ways!) and
2.3.32 from Kaczor and Nowak V.2, and August 95 #3. Erica Whittaker
points out that I left out an important detail in the solution to
August 95 #3: to show that G(x) \leq 0 so that 0 \geq G(x) \geq -log 2.
This follows from the fact that for fixed s, log(s) is less than
log(s+t), for t in (0, \infty). I also wanted to solve problems 2.3.40
and Spring 99 #3 but ran out of time.
