Homework:


Homework for this course consists of two types: online homework and hand-graded homework. The online homework is based on the WileyPLUS system. Most online homework is due Friday 11:45pm. The hand-graded problems come from three resources: textbook problems, supplementary problems, and Matlab projects. Hand-graded homework will be collected every Thursday in class. Weekly homework assignment will be published on the course webpage.

No late homework will be accepted.

 

Homework should be readable and stapled. Illegible scribbling will receive no credit from the grader. For Matlab projects, you should hand in the printout of your Matlab session, including the source code and the generated graphs. You are encouraged to discuss with your classmates. However, your write-up must be independent. Homework assignments of high similarity will receive no credit.

 

This part is based on the WileyPLUS online homework system. To use this system, you need to register following the instructions in the student flyers. See "Announcements" above.

2.   Hand-graded homework problems.
These problems are to be turned in and graded by the grader. A list of the hand-graded homework problems (as well as a list of the online homework problems) can be found in this assignment sheet.
Hand-graded homework problems include three categories:

Textbook problems;

Supplementary problems ;

Matlab projects; Project 1, Project 2 , Project 3 .

For example, in the assignment sheet, "2" means Problem 2 of the corresponding section in the textbook; "A" means Supplementary Problem A; "Project 1" means the Matlab project 1. Note that "supplementary problems" are mandatory, not optional.

 

Weekly homework assignments are listed below. They can also be found in the assignment sheet.
