====== Announcements ====== ---- == Unofficial course grades == Unofficial course grades are {{:4214-grades.pdf|here}}. ---- == Problem Set == Question 6.5 (the one with the missing figure) is hereby removed from the problem set. Question 4.2 (the other one with the missing figure) -- here it is: {{:scan-small.jpg}} ---- == Lab 4 posted == Lab 4 has been posted on the [[documents|Documents]] page. NOTE: The original version of Lab 4 contained typos. These have been corrected. Please **clear your browser cache** before reloading. ---- == Quiz 3 and 4 == Quiz 3 and 4 will now take place simultaneously on Thursday, Feb 12. The quizzes will be based on the review problem set, posted below. If you need a copy, please drop by my office. Quiz 3 will be based on problems from Chapter 4, and Quiz 4 will be based on problems from Chapters 6 and 7. ---- == Grade Calculation Changes == As mentioned in class, grade calculation has been slightly changed. The "lab" component of your grade will now be calculated as follows: your best three of the four labs will be assigned a weight of 5.33% each, and your worst of the four labs will be dropped from your grade. In practice, this means Lab 4 is still optional, since not handing it in will give you a grade of zero, which will guarantee that it will be dropped from your grade. However, you might also choose not to hand in Labs 2 or 3, or you can hand in all the labs to ensure that your best work of the four is chosen. ---- == Quizzes 3 and 4 == Quizzes 3 and 4 will be held simultaneously on Tuesday, February 10. These will be review quizzes, to help you get caught up, focusing only on material from before the break. ---- == Review Problem Set == If you have a copy of the textbook, here is the review problem set: * Chapter 4: 4.1, 4.2, 4.7, 4.9, 4.14, 4.16, 4.17, 4.19, 4.27 * Chapter 6: 6.4, 6.5 * Chapter 7: 7.1, 7.2, 7.3, 7.4 Also, you can look at the old problem sets on the [[Documents]] page. If you don't have the textbook, drop by my office for a copy of these questions. ---- == Due Dates and Labs == All outstanding due dates are hereby changed to the last day of class in the fall term. Lab 4 is now optional. It will be posted shortly. ---- == Lab 3 == Lab 3 has been posted on the [[Documents]] page.

It is due on November 6. ---- == Extension on Lab 1 == The due date for Lab 1 is extended to Oct 23. ---- == Clarification on the problem set == I've had several questions about #2b from Problem Set 2.
