21-260: Week #5

I've posted the reading and homework assignments for Week #5. As I mentioned in class, there is no written assignment this week. There is an online assignment. I said in class that it would be due on Friday, but I've changed the deadline to Sunday evening, because... Well because there was no reason not to.

21-260: Exam Strategy

I just responded to a student email asking about studying for the exam, and what type of exam you can expect. This is what I wrote:

I would say that working through practice problems is the best way to prepare. You should also review your class notes, and especially your graded homework. When you are working problems, keep track of things you need to look up or ask about. Those are things you should focus on as the exam date gets closer (as it is now!)

On the day of the exam, I would recommend taking a couple minutes to read over the whole exam. Sort out which problems look easy, and which look more challenging. Finish the easiest problems first, leaving you more time to think about the harder problems without distractions.

Regarding the makeup of the exam. You can expect 20-25% of the exam to be pretty straightforward, and another 20-25% to be pretty challenging. The rest somewhere in between. There will be some conceptual material, like on the written homeworks, but most of the exam will be more computational.

21-260: Exam Odds and Ends

As announced in class today, our first midterm is this Wednesday from 7:30-8:20 in UC McConomy. There will be no class on Wednesday. I will hold a review session tonight from 6:30-8:00 in PH 100.

I've added "Systems of Differential Equations (Section 7.1)" to the list of topics covered. That is what I've been telling people all along, but I inadvertently left it off the list. I also added 7.1.23 to the practice problems from the text.

21-260: Week #4 WileyPLUS Assignment

I've had to remove two problems from the WileyPLUS assignment for this week. Problems 2.7.1a and 2.7.18b were left over from a previous version of the course. We are not covering Euler's method this semester. I thought I removed all those problems before posting the assignment, but these two slipped through. Sorry to anyone who has been working on these problems, and sorry to anyone whose access to the site was interrupted while I edited the assignment.

21-260: Correction to HW#4

Thanks, everyone who pointed out the repeated problem on this week's assignment. I've corrected the assignment page. The correct problems are 2.5.20, 2.5.25 and 7.1.22. I also corrected the quotation marks so they would come out correctly.
