## 175, 275 -Midterm 2

November 2, 2008

The second exam was Friday, October 31, during lecture. This exam is worth 10% of the total grade, and replaces the grade of the first exam if the new score is higher. As before, books, notes, and calculators were allowed.

Failure to take the exam was graded as a score of 0.

175: The midterm covered Chapter 7 of the textbook (and assumed knowledge of Calc I).

275: The midterm covered Chapter 12 of the textbook (and assumed knowledge of Calc I and II).

Below is a graph of the function in problem 5 of the 275 midterm.

## 175, 275 -Suggestions for next week.

October 21, 2008

Remember that on October 31 is the second midterm. There will not be a homework set due on November 4. However, we will cover new material during the final week of October. If you want to read ahead, in 175 we will be covering the beginning of Chapter 8, probably up to section 8.3. In 275, we will be covering the beginning of Chapter 13; I doubt we will get to section 13.4, but you may want to start reading the first 4 sections of this chapter.

The exam will concentrate on material covered after the first midterm, but it is cumulative. For 175, it will include the basics of Taylor’s theorem (and it may be a good idea to take a look at Talman’s paper; see here); but it won’t include the proof that the method of partial fractions decomposition works. For 275, you may want to review the polar expression of the Laplacian and how to derive it. For both courses, a safe assumption is that if something was covered in lecture (up to October 24), then it may be included.

September 30, 2008

The first exam was Friday, September 26, during lecture. This exam is worth 10% of the total grade. Books, notes, and calculators were allowed.

Failure to take the exam was graded as a score of 0.

175: The exam covered Chapters 6 and 9 of the textbook (and assumed knowledge of Calc I). Exam, Graph.

275: The exam covered Chapters 10 and 11 of the textbook (and assumed knowledge of Calc I and II). Exam, Graph. (Typo: In problem 2.d, the equation of the plane must be $x+y-2z=2$.)
