Math 307, Section I

Grades: to compute your grade, I rescaled your homework total so it was out of 50 points, and rescaled your final so it was out of 150 points. Then I added together your midterm scores (plus revisions, if you did them), your rescaled homework total, and your rescaled final, to get a score out of 400 points. Then your grade is given by the formula
```
   grade = 2(total - 252)/110 + 2.0
	
```
The final exam was on Wednesday, December 18. Solutions are available.
- The median was 68.
- The average was 65.0.
- I probably won't be in my office much until January 6. You can stop by my office and pick up your exam in winter quarter.
The second exam was on Wednesday, November 20. Solutions are available.
- The median was 85 (87.5 after revisions).
- The average was 83.0 (86.5 after revisions).
- Very approximate grade lines: 2.0 corresponds to 70, 3.0 corresponds to 80, 4.0 corresponds to 90.
The first exam was on Monday, October 21. Solutions are available.

I've posted some graphs of solutions to undamped and damped mass-spring systems, to illustrate what I was talking about in class on Friday, November 8.
Here is the table of Laplace transforms that I handed out in class, with added lines for e^at sinbt and e^at cosbt.

The homework solutions (etc.) are PDF files. One way to read these is with a program called "Adobe Acrobat Reader". This program may already be installed on your computer; if not, it is available, for free, for a variety of platforms, from Adobe's web site. (Other ways to view PDF files: ghostview, gv, gsview and xpdf.)
