Course Objectives
The course provides fundamentals of Ordinary Differential Equations (ODEs) and systems of ODEs with an emphasis on engineering applications.
Grading Policy
Homework: (see more on the Homework tab)
- Homework will be due weekly at the beginning of class on one of the class days. Homework will be posted online (see the Homework Assignments tab). Late homework is NEVER accepted. For each homework, a selected set of problems will be graded. The graded homework will be returned to you in lab sections. Please print your name, lab section number, and Student ID clearly on the first page of your homework.
Quizzes: (see more in the Homework tab) -- All quizzes will be given in Lab sections.
- AMS 20 students: there will be six quizzes for AMS 20.
- AMS 20A students: only the first three of them (Quiz 1 ~ Quiz 3) are required for AMS 20A.
Two in-class exams: (see more in the Quizzes and Exams tab)
- Midterm exam (only for AMS 20): Feb 13, Tue, in-class.
- Final exam (both for AMS 20 and AMS 20A): Mar 22, Thu (8 am -- 11 am).
Grading:
- AMS 20 :
- Method 1: Homework 20%, Quizzes 10%, Midterm 30% and Final 40%
- All class activities (classes, labs, six quizzes, homework sets, midterm and final exams)
- AMS 20 students can drop one lowest homework score and one lowest quiz score.
- Method 2: 100% Final only
- Final grade = max (Method 1 score, Method 2 score)
- AMS 20A: Homework: 30% Quizzes: 10% Final 60%
- All class activities (classes, lab sessions, quiz 1 ~ quiz 3, homework sets) for Week 1 ~ Week 6
- No midterm exam
- Final exam only on the topics for Week 1 ~ Week 6
- AMS 20A students can drop either one lowest homework score or one lowest quiz score.
- Required participation:
Curving: There will be a curve of your final grade. The policy on curving is such that the class average will be decided to be between C+ and C.
Passing grades: Your overall curved score must be C or above in order to pass the class.
Academic Honesty (zero-cheating policy):
- Any form of cheating or dishonest academic activities (using notes, books, smartphones, tablet PCs, or electronic devices; copying from someone else, etc. on in-class quizzes or exams) will not be tolerated and such students will receive a failing grade. Any students with such activities, if caught by the instructors or classmates, will be reported to the AMS department and her/his college provost.
