 Syllabus


Calendar:
This provides a rough schedule for the semester. The sections to be
covered and the dates and order in which they occur are subject to
change.


Assignments:
These problems are to be turned in for a grade.


Supplemental
exercises: These exercises provide extra practice on the basic
methods and concepts covered in a given section. You should complete
as many as necessary to master the given technique. They will not be
graded. Do not turn these
in.


Keys
to quizzes and exams 

Basic
derivatives and integrals: You may use this for exams.

Wed 12/7: here is what's been
suggested as possible
questions for the final exam.

Tues 12/6: Office hours this
week: Wednesday 11:303:30, Thursday 1:003:00, Friday
11:302:00. On Wednesday and Friday I will be coming from a class,
so I may be a little late getting back to my office. If I'm not in
my office during these times, I've probably stepped out to get
coffee and will return shortly.

Sun 12/4: The plan for this week
will be as follows. Monday will be devoted to questions about the
Laplace transform (particularly in the context of discontinuous
forcing functions and the Dirac delta function) and a couple of
short exercises to help get you into "review mode".
Tuesday will be an open session; bring questions. At the end of
class on Tuesday, there will be time for you to check the homework,
quiz and exam scores I have entered for you in my spreadsheet.

Mon 11/28: I will try to come in
early tomorrow (around 12:40) to explain problem # 6 in section 5.4.

Sun 11/13: A table of basic
Laplace transforms is posted above. You should print this off for
use during the remaining quizzes and exams. Also, a review of
partial fraction decomposition can be found here.

Tues 11/1: I've opened a forum
on the Blackboard discussion board for people to list the questions
they would like to discuss during the review on Wednesday. The idea
is try to reach a class consensus about what people want to talk
about before the review.

Mon 10/31: There's a "typo"
on the key for quiz 7 #2b. The eigenvalue should be \lambda = 3, not
\lambda = 3 as written.

Mon 10/10: Tomorrow's quiz will
be over the material of sections 3.2 and 3.3 only. Assignemnt 6 (due
tomorrow) will comprise the assigned problems from sections 3.2 and
3.3 only. Problems from section 3.4 will be due next week with
assignment 7.

Thurs 9/29: The scores for the
first exam (out of 70 points total) and an estimate the current
course "grades" (percentage) have been posted on
Blackboard. The
"grades" were computed as follows:

Add the first four quiz scores, divide by 40 and multiply by 0.3;

divide the first exam score by 70 and multiply by 0.6;

add the first four homework scores, divide by 8 and multiply by 0.1;

add 1, 2 and 3, and multiply by 100.
 Example: quiz 1 = 7, quiz 2 = 8, quiz 3 = 5, quiz 4 = 6; exam =
55, hw 1 = 2, hw 2 = 1, hw 3 = 0, hw 4 = 2:


[( 7 + 8 + 5 + 6 )/40]*0.3 + [55/70]*0.6 + [(2 + 0 + 1 + 2)/8]*0.1 =
0.7289

0.7289*100 = 72.89


If I were to assign letter grades now, the breakdown would be:

A: 89  100

B: 78  88

C: 68  77

D: 60  67

F: below 60

Thurs 9/22: The review for the
first midterm has been posted.

Mon 9/19: Tomorrow in class, we
will cover integrating factors in the context of exact equations.
After that, there will be open time for questions and discussion.
Open season  including past homework problems.

Sat 9/3: For those of you who
like to read ahead, we will be making the following changes to the
calendar. On Tuesday 9/6, we will cover sections 2.1 and 1.2  in
that order. Section 1.4 will not be covered in class, although
readings and problems from that section may be assigned for
homework. We will try to cover section 1.3 later in the semester.

Tues 8/30: Office hours have
changed (see above).

Thurs 8/25: Homework
formatting. At the top of the first page of each assignment, please
include:

your name

the course and section numbers

my name

the assignment number

the due date of the assignment
 in
that order, and each on a separate line. Begin each section on a new
page, and clearly indicate the section number at the top of the
page. Do not divide your pages into multiple columns (if you have
already begun writing up Assignment 1 and are using more than one
column per page, you do not need to recopy your work).

Tues
8/23: There is now a
discussion
forum open on Blackboard.
You can subscribe to the forum and receive emails at your Boise
State account as new posts are added. I've started with a "general
discussion thread". You may also begin new threads within the
forum  for example, if you want to discuss a particular homework
problem.

Sat 8/20: The syllabus and calendar are now posted.

Wed 5/11: Welcome to Math 333.
