Conflict exam is handled directly by the University Registrar's Office, rather than through me or the Math Department. Go to ELion for more detail. Assignment #10 will be given in class on Friday, March 22. It is due at the beginning of the class on Thursday, March 28. 3112013: Here is an experimental howto guide of using the second translation theorem of Laplace transforms, that I mentioned in a couple of my sections, using examples with colorcoded parts. (It works better if you print it out in colors.) Notes, worksheet, and a reference chart, on chapters 7 and 9, they cover the rest of the topics that are going to be on the second midterm exam:
Inclass worksheet set 4  covering systems of differential equations, and phase portraits (Chapters 7 and 9). If you have a scheduling conflict with our second exam and need to arrange to take either the conflict exam (same day as the regular exam, but from 5:05 to 6:20pm), or the makeup exam (on Monday, April 8, from 6:30 to 7:45pm), please come to see me before or after class.

It is due at the beginning of the class on Thursday, April 11. 3252013: Midterm Exam II study guide Here is a set of exam II review formula sheets made by a fellow student back in 2011. I include it here because it might proved to be helpful to you as well. Note that it includes mechanical vibrations and higherorder linear equations, which will not be on the second exam (the first exam covered those topics)
3272013: Notes and worksheet on Chapter 10  Partial Differential Equations: 4112013: Assignment #13 will be given in class on Friday, April 12. It is due at the beginning of the class on Thursday, April 18. How the 100point homework score is calculated: There are going to be 13 assignments total, each is worth 10 points. Basically, the top 10 scores are kept, for a total of 100 points. But, there is an exception  the last 2 assignments (#12 and #13) on PDEs cannot both be dropped. At least one of the 2 scores must be included in the calculation, even if the score were zero. There are 2 reasons for this exception. The first is that PDEs is, literally, the fourth credit (above Math 250's) of the course, so at least one score from a PDE assignments should count. The second is that, in the past many students who had scored well in the first 10 assignments elected to skip the last 2 or 3. Essentially, they decided to ease up on class work during the most difficult part of the course, and at the most critical moment just before the final exam. This complacency usually did not turn out well for the students. Remember, now is not the time to ease up because more than half of the final exam is going to be consisted of PDE / chapter 10 topics. This rule would, hopefully, make sure everyone are to spend sometime studying chapter 10. In addition to the Penn State Learning's exam review (detail see below), I will personally have a review session on Sunday, April 28, from 1:00 to 3:30pm, in room 262 Willard. 4222013: Penn State Learning's peerlead review session detail: this Saturday, April 27, starting at 12:00pm, in 104 Thomas Bldg. So there are 2 review sessions this weekend, mine on Sunday at 1 pm, and Penn State Learning's on Saturday at 12 pm. Suggested sample final exams: first do the following  Fall 2012, Spring 2012, Summer 2011, Fall 2010, Spring 2009; then you can also try  Fall 2011, Spring 2011, Spring 2010 (answer keys available to all).
