Grading Policy: Your course grade is the sum of following performance scores: The homework will count as

15% of the course grade; the in-class quizzes will count as 25%; the midterm will count as 30% and the final

exam will count as 30%.

Quizzes:  Usually Wednesday's classes will take the form of a problem session, followed (most weeks) by

a short quiz. Sometimes a quiz may be arranged on Tuesday or Thursday depending on teaching

speed.  There will be five or six quizzes.  Your lowest quiz score will be dropped. Remaining quiz scores will

be averaged and contributed to the course grade. There is no make-up quiz. In order to encourage students to

answer questions in class, 1-3 % of the following quiz score will be given to a student depending on how the

student initiatively, vigorously and correctly answers the instructors questions or example problems.

Exam:  There are two midterms and one final exam. UO ID is needed for each exam. However, cell phone,

advanced calculator and lecture notes are not allowed on each exam. During the exam students are prohibited

from looking at other students exam, talking to other students and giving or receiving unauthorized help on

exam without permission from the instructor. Otherwise, an appropriate academic sanction may be given.

Academic misconduct is defined in The University Student Conduct Code(conduct.uoregon.edu). For each

exam (including quizzes), you can bring a 3x5 inch index card with formulae or useful notes for you. Your

solution to each exam problem should be legible and describe your ideas clearly. No details will have no

scores. Midterm and final exam dates and times are specified and can't be changed. There are no make-up

exams.


Homework:  Homework questions and due dates are posted in the following Tentative Syllabus of this web

page which will be updated very often. Homework is due weekly before 3:00pm of each Thursday or the

date specified in the Tentative Syllabus. It is your responsibility to check the updated Tentative Syllabus

each Wednesday afternoon or the date before the specified due date in the Tentative Syllabus. Late handing

in homework will not be accepted.   One lowest homework score will be dropped and the remaining

homework scores will be averaged and contributed to the course grade. You can discuss with other students

while working on your homework problems, but copying other students' answers is not allowed, otherwise a

penalty of score deduction may be given. Your solution to each homework problem should be legible and

should describe your ideas clearly. No details will have no scores.  Please use 8.5" by 11" sheets to do your

homework and don't forget to write down your first name, middle name and last name (In order to protect

your rights to confidentiality of your papers, don't write down your student ID number on homework paper.)

on each page. Your homework will be returned in the class.  Poor attendance may alter this policy; see

"Attendance" below.

 

Attendance:  Attendance is mandatory.  You are responsible for all the announcements, changes, course

information, and topics that I cover in class. If you miss a substantial number of lectures without

discussing the matter with me and without a valid excuse, a penalty of score deduction of homework and

quizzes  may be given according to number of lectures missed.

 

Course Outcomes: A successful student of this course should be able to understand the great idea of

limit, which brings motion into mathematics, use the limit operation, find the differentiation of different

functions, model related practical problems, such as maximum or minimum value problems and

optimization problems, and solve the problems by differentiation.
