HW due: §3.9 #41 (see hint below); pp. 172-173 #3, 4, 9,
19, 22, 24, 38, 39, 46, 58-62 all.
Hint for #41: If you mark the unknown
point of tangency as (x, ex), as we did in class
yesterday, you may confuse yourself when you try to write the general
equation of the line passing through that point. The reason is that a line of
form y = mx + b assumes that x is an independent value, not a
single fixed unknown value. Therefore, if you try to use x in two different roles at the same time, you will probably
confuse yourself. Suggestion: Mark the unknown point of tangency as (k, ek)
where k represents an unknown
constant.
You need two things to write an equation of a line: its slope and its
intercept. The intercept is easy (think about it), and the slope of the line
is such that it must match the slope of the exponential curve at the point of
interest. So . . . write an equation that says that those two slopes are
equal.
This should be enough to get you over the hump. If not, then I expect to hear
from you.

Quest (70 pts.) on Chapter 3. Problems will be similar to yesterday’s HW assignment
but may be in a short-answer format to facilitate grading. Warning: That means that there will be
little or no partial credit. You may use your calculator to check your work
for reasonableness.

HW due: Rewrite your entire quest
from yesterday, even the problems that you think you did correctly. If
you have any additional comments for #1, please write them as well, but that
is optional.
Honor Code Notice: You may work
with other students. However, you may not copy another student’s work. All
work must be your own. A good guideline is to make sure that whenever your
pencil is in motion, your eyes are on your own paper, not someone else’s
paper. If you work in groups, all members of the group must participate.
“Leeches” or “lurkers” who piggyback on other people’s work without
contributing anything substantial of their own are cheating as far as this
assignment is concerned. Knowingly allowing someone to be a leech is also an
honor issue. Don’t let anyone look at your homework paper unless you are
standing right there. Suppose someone says, “Say, could I borrow your paper
for a while?” Your response to him should be
(A) “Sure! I always support my fellow student.”
(B) “Sure! I don’t know if this will help you, but feel free to borrow it and
look it over.”
(C) “Sorry, I don’t ever work with other students.”
(D) “Let’s ask Mr. Hansen what he thinks.”
(E) “That’s an interesting question. Is there a time we can sit down and work
together on this assignment?”
Answer: E. (E is better than D because
it shows more proactivity.)
