#### 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.

- HW1(Due: July 1 @10:39AM)
- 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]

- HW3 (Due: July 15 @10:39AM)
- 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.

- HW5 (Not Due)
- HW6 (Due: August 26 @2:39PM)
- 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

- 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.
