General Information

Handouts and Course Material

Problem Set

Note that, for each HW, only ONE question will be graded. Of course, you do not know which one will be selected; so you should work on all of them.

  1. HW1(Due: July 1 @10:39AM)
  2. HW2(Due: July 8 @10:39AM)
    • Because we haven't talked much about mesh analysis, you may submit Q5-Q9 with the next HW. In which case, submit Q1-Q4 on July 9 and then submit Q5-Q9 on July 16.
    • Of course, if you feel comfortable solving Q5-Q9 at this time, you may submit them on July 9.
    • Solution[Posted on July 8 @ 3:30PM]
  3. HW3 (Due: July 15 @10:39AM)
    • Q5-Q9 from the previous HW are now Q1-Q5 in HW3. If you have already worked on them on HW2, clearly indicate this fact in your HW3.
    • Solution[Posted on July 15 @ 10:30PM]
    • Comments[Posted on July 30 @ 1:30PM]
  4. HW4 (Due: July 22 @10:39AM)
    • Solution [Posted on July 23 @ 4PM]
    • Scores for HW1-4 are posted. [Fixed on July 29 @ 9:30PM.] The leftmost column contains the last three digit of your student IDs.
  5. HW5 (Not Due)
  6. HW6 (Due: August 26 @2:39PM)
  7. HW7 (Due: September 2 @10:39AM) [Fixed on August 26 @ 10:30PM]
    • If you have already downloaded the earlier version of HW7, ignore Q4 and Q5. We haven't covered Q4 and Q5 in class.
    • Solution
  8. HW8 (Due: September 9 @ 10:39 AM) [Fixed on September 3 @ 9:00AM]
    • If you have already downloaded the earlier version of HW8, ignore Q7 to Q10. I already talked about them in class but we will work on some more examples next week.
    • Solution (draft)
  9. HW9 (Due: September 16 @ 10:39 AM)
  10. HW10 (Due: September 23 @ 10:39 AM)
  11. HW11 + self-evaluation form (Due: September 30 @ 10:39 AM)
