**Grade:**

Grades are determined as follows:

Online quizzes 20%.
There will be one quiz each week starting on Thursday, September 14. Each quiz will start on a Thursday and end on Wednesday. Each quiz will have ten
questions from the database which is available in the practice quizzes. The questions are chosen randomly,
so different students will have different
questions.
Online practice quizzes (if you are
using a pop-up blocker, you may need
to turn it off). You must start a graded quiz by 11 pm on the day of
the deadline. Graded quizzes are named
YRenardy1, YRenardy2, etc. A table listing how practice quizzes
correspond to sections in the text.
Rules to follow to avoid technical
problems when taking a graded quiz.
Please login to the practice quiz system with your Virginia Tech PID and Password, and log off when you are finished practicing. This server has no
connection
to the testing server, which means that you will not risk losing any graded work if you forget to quit your browser. It also means that these practice
problems will not be available when you view past tests. If you want to review your practice quiz problems later, you can mark up to 30 individual problems
using the link below each graded practice problem. There is a link to your list of marked problems available anytime you are in the practice problem system.
The following is a list of quizzes and their deadlines. The practice quizzes covered in each quiz will be added as the date of the
quiz approaches:

Quiz 1: 9/20

Quiz 2: 9/27

Quiz 3: 10/4

Quiz 4: 10/11

Quiz 5: 10/18

Quiz 6: 10/25

Quiz 7: 11/1

Quiz 8: 11/8

Quiz 9: 11/15

Quiz 10: 11/29

Quiz 11: 12/6

Quiz 12: 12/13

Written homework assigned from the list is handed in at the beginning of the
next class: 20%. Only selected problems will be graded; the rest of the work
will not be marked. Please check the correctness of your homework solutions by comparing with the
solutions posted. Please do not expect credit for correct answers if no
work is shown or if the reasoning is incorrect. If you come in late, hand it in immediately when you come in. You can
use any software to check your work or hand-drawn plots (e.g., phase plane plot).

Two in-class midterm tests, 20% each, closed book, no calculators, no cell phones. Bring pen or pencil and clean paper.
The final exam is 20% and is cumulative. The location is TBA. The first hour is multiple choice, common to all sections, and the time/date takes precedence over other exams.
Bring #2 pencil. The second hour is written work. Closed book, no calculators, no cell phones.
A final letter grade is determined as follows: 90% is at least an A, 80% is at least a B,
70% is at least a C, 60% is at least a D, and below 50% is an F.
An unexcused absence from a scheduled test or final exam results in a zero
score; excused absences must be cleared through the office of the Dean of Students
before the test. There are no make-up tests; the final exam score replaces an
excused test.
**IMPORTANT:**
Please check that you are registered for this section.

**Virginia Tech Honor System Information:**

The Undergraduate Honor Code pledge, by which each member of the
university community agrees to abide, states: "As a Hokie, I will conduct myself with honor and
integrity at all times. I will not lie, cheat, or steal, nor
will I accept the actions of those who do."
Students enrolled in this course are
responsible for abiding by the Honor Code. A student who has doubts about how
the Honor Code applies to any assignment is responsible for obtaining specific guidance from the course instructor before submitting the assignment for
evaluation. Ignorance of the rules does not exclude any member of the University community from the requirements and expectations of the Honor Code. For
additional information about the Honor Code, please visit: https://www.honorsystem.vt.edu.

**Student Responsibility**

Review your prerequisite derivatives and integrals from calculus, and eigenvalues/eigenvectors from linear algebra.
Class attendance.
Attendance records are taken but not included in the grade.
Communication. Participation.
Collaboration when permitted.
Class hours total 2.5 hours a week. Your independent work is usually more than 7 hours a week. Invest the
time.
Focus on the mastery of recognizing the type of equation you have, and which method to use, and carry
out the calculations through to the end.
**Special needs:** Students who need adaptations or accommodations
because of a disability (learning
disability, attention deficit disorder, psychological, physical, etc.), or
have emergency medical information to share with me, or would need
special
arrangements in case the building must be evacuated, please feel free to
meet with me to discuss what can
be done to help fulfill the requirements of the class. Also, they may
contact the Dean of Students who will see that
their special needs are appropriately addressed. Students
requiring testing
accomodations must work through the appropriate university offices; http://www.ssd.vt.edu/index.html.
Any
paperwork must be
