Class TA:
Rose Friend (vfriend2@gsu.edu) - our course TA is available for office hours and
will assist in grading of quizzes and semester tests.
Office Hours: Limited on-campus, in-person office hours will be available only by
appointment.
• Instructor’s office hours will be held MW 3:30 – 4:00 pm via WebEx at
https://gsumeetings.webex.com/meet/hliu16.
• TA’s office hours will be held MW 11:30 am – 12:30 pm via WebEx at
https://gsumeetings.webex.com/meet/vfriend2.
Grades: Grades will be determined on the basis of 3 tests (15% each), average of online (MLM)
homework (10%), in-class quizzes (15%), class attendance (5%), and the final exam (25%). All
students must take the comprehensive final exam. If the final exam grade is better than your
lowest test grade, then that test grade will be replaced by the final exam grade. Letter grades will be
awarded as follows:
97%-100% → A+
93%-96% → A
80%-82%
77%-79%
1
→ B→ C+
90%-92% → A-
70%-76%
→ C
87%-89% → B+
60%-69%
→ D
83%-86% → B
Below 60% → F
Note: To allow for emergency situations and unforeseen circumstances, students are allowed to
miss 2 classes without penalty. Please note that late registration is seen as an unforeseen
circumstance and any missed classes, due to late registration, will be counted amongst the class
sessions that the student is allowed to miss. At the end of the semester, the lowest two quiz
scores will be dropped.
Example of Final Grade Computation:
Test Grades: T1 = 88, T2 = 72, T3 = 68; Homework average = 95; Quiz average = 85;
Attendance = 90; Final Exam = 79;
Final Grade: 0.15*(88+72+79) + 0.10*95 + 0.15*85 + 0.05*90 + 0.25*79 = 82.35, which
rounds to 82, which is a B-. (Note the replaced grade for Test 3.)
Attendance Policy: Attendance is crucial for your success in this course. Attendance will be
taken daily. It is your responsibility to always record your attendance in class. In order to gain
attendance credit for any particular scheduled day, you must remain in the classroom during
your entire class session. If you are significantly tardy for class or leave early, your attendance
for that day will not count.
Note: GSU has a new process for students seeking excused absences through the Dean of
Students Office. Please submit documentation to https://deanofstudents.gsu.edu/studentassistance/professor-absence-notification/. The professor will then be notified by the Dean of
Students of any excused absences.
Makeup Policy: There will be no make-up quizzes or exams except in extreme cases of
documented and verifiable medical necessity (e.g. a professor absence notification from the
Dean of Students Office). Any missed quizzes/exams will result in a grade of zero for the
quiz/exam. Missing the final exam will result in a grade of F for the course unless arrangements
are made prior (at least one week if possible) to its administration.
Writing in mathematics: Your grades on all written assignments will be based on clear
presentation as well as correct mathematics. It is often a good idea to model your writing on the
examples worked in class or posted online. If you are unsure of whether or not your written
work is acceptable, you should ask about it. Some of the problems chosen for written
assessments will require you to use two or more concepts together to solve a problem you have
not yet seen before. This means you should make every effort to gain a strong understanding of
the concepts in addition to working example problems. Please be aware that the process, and
not merely the final answer, is critical to your understanding of the material and your success in
the course. Precise, effective writing will be rewarded. Careless or incomplete work will be
penalized, even if by chance it leads to a correct numerical answer. This means your final
answer is worth less than the procedure you used to get your answer.

Unauthorized Public Posting and Distribution: The selling, sharing, publishing, presenting,
or distributing of instructor-prepared course lecture notes, videos, audio recordings, or any
other instructor-produced materials from any course for any commercial purpose is strictly
prohibited unless explicit written permission is granted in advance by the course instructor.
This includes posting any materials on websites such as Chegg, Course Hero, OneClass, Stuvia,
StuDocu and other similar sites. Unauthorized sale or commercial distribution of such material
is a violation of the instructor’s intellectual property and the privacy rights of students attending
the class, and is prohibited. Failure to abide by these limitations constitutes a violation of the
Policy on Academic Honesty and will be treated accordingly.
Disruptive Student Conduct in the Classroom or Other Learning Environment: The
University’s disruptive student policy applies and students should familiarize themselves with
the relevant parts of the student code of conduct at: http://codeofconduct.gsu.edu/. Arrive on
time, and do not leave early. If you must leave early for some reason, please inform the
instructor prior to class and do so as quietly as possible. Turn off all pagers and cell phones
before entering the classroom – having these items “go off” in class is considered disruptive
behavior. Any type of inappropriate conduct may result in your being administratively
dropped/withdrawn from the course.
Cheating/Plagiarism: Cheating/plagiarism will not be tolerated on any work. A first occurrence will
result in a grade of 0 on the assignment for all concerned parties as well as an Academic Dishonesty
form being filed with the Dean of Students. A second occurrence will result in a grade of F for the course
for the concerned parties and a second Academic Dishonesty form being filed.
Inclement Weather Policy: If the University is closed due to inclement weather, any exam that may
have been scheduled for that date will be administered on the next available class date. If an assignment
is due that day (or if you are scheduled for an exam), it will be due the next class.
Withdrawal Policy: If you withdraw from this class on or before the Midpoint of the semester (March
1, 2022), you will receive a WP regardless of your performance. The computer will then turn this into a
W or a WF depending on how many cumulative withdrawals you have in the University. Voluntary
withdrawals after the Midpoint are not allowed.
Accommodation: Students who wish to request an accommodation may do so by registering with
the Access and Accommodation Center (AACE). Students may only be accommodated upon issuance
by the Access and Accommodation Center of a signed Accommodation Plan and are responsible for
providing a copy of that plan to instructors of all classes in which accommodations are sought.
Evaluations: Your constructive assessment of this course plays an indispensable role in shaping
education at Georgia State. Upon completing the course, please take time to fill out the online course
evaluation.
THIS SYLLABUS PROVIDES A GENERAL PLAN FOR THE COURSE; DEVIATIONS MAY BE
NECESSARY.
