Here are some additional problems with solutions. Also,
review the Nov. 18 test and its solution key, since some of those types of
problems (not counting the proof of the Change of Base formula) will be
recycled.

Test on Chapter 6, Excluding §§6-13 and 6-14. To assist you in studying, I have posted some good
practice problems with solutions above.

No class (House Tour).
However, watch this space for an announcement regarding your test scores.
After I get the tests graded, I will make a decision regarding whether to curve
the scores or (if warranted) run a new test next week. If I were you, I would
prepare for a half-period re-test on Monday.

HW due: All students (even Joe M. and Ron L., who were absent on
Thursday 12/1) must correct Thursday’s test
to 100%. You must show all work. You may confer with parents, tutors,
or friends. I recommend that you take the test under time pressure, in a
quiet room, so that you can practice the pressure of an actual testing
situation.
After taking the test, use the answer key to
score yourself. The answer key does not show all steps—you must provide those
yourself. Keep revising until you have a perfect test. If there are problems
that you stumbled over, you will probably want to devise similar problems and
practice them under time pressure as well.
Also today: Re-test (half period)
will occur after you have had a chance for your questions to be answered.
Everyone is required to take the re-test, but the re-test will help you the
most only if your HW assignment for today is excellent. If your HW is sloppy,
incomplete, inaccurate, or the result of spotty knowledge when I check it,
then you will still have to take the re-test, but it will not help you as
much. To make sure that you have not simply copied HW from someone else, I
will orally quiz people at random to see if HW knowledge is solid or spotty.
Scoring: If your HW is excellent,
then the higher of the two test scores will count. If your HW is not
excellent, then the two test scores will be averaged—a less desirable outcome
for you.
Weather: If school is cancelled
Monday because of snow, then the re-test will occur on Tuesday. Both Monday
and Tuesday are currently open for Form IV tests (i.e., not overscheduled).
Additional information: Although I
have the scores for Thursday’s test, I will not give you your score until
class time. You do have the questions and the scoring key (see links above).
The statistics for the original test are shown below. All scores include an
8-point bonus for late start.
n = 17
s = 13 (standard deviation, a
measure of dispersion; typical value is 10)
mean = 70.4 (typical value is 77, which means this test was harder than
usual)
median = 69 (typical value is 77; the fact that the mean is higher than the
median signifies that the scores were skew right, i.e., bunched up in the
lower half of the distribution)

Since there is no school today, here is the randomly determined backup phone schedule
for “mini-tutorials” and HW checks. At your appointed time, please be waiting
by your telephone with your notebook and textbook open and ready to discuss.
If there is some emergency that causes you to leave your house, please leave
an explanation at 703-599-6624 with a statement of your phone number and a
time at which you can be reached. You can also use that number for leaving
word of additional questions you have or requests for help.
Please do not send me e-mail today, since I will be on the phone nearly the
whole time. Instead, leave a message for me at the number given above.
