The homework of the course consists of the following two types:

  • Online homework problems.

    We use the WebAssign online homework system.

  • Hand-written and graded Homework

    These problems will be turned in and graded by a grader. A list of hand-graded homework set for MA 266 (as well a list of online homework problems) can be found at assignment sheet .The hand-graded homework contains three parts:

  • The textbook problems.
  • Supplemental problems.
  • Three Matlab projects:Project1; Project 2; Project 3.
  • (Note: in the assignment sheet, "1" refers to Problem 1 in the text book; "A" refers to Problem A in the supplemental problems; and "Project 1" refers to Matlab project 1.) No late homwork will be accepted.
  • Actively participating in class and working on extra credit problems will help improve your grade.
