# Exam Information for Math 319/320

## Fall 2008

As it says on the course syllabus, there are two midterms and a final in MAT319/320, which count for 25%, 25%, and 35% of your grade, respectively. No Make-up exams will be given. If you miss an exam due to a documented medical or family reason, that score will be replaced by the grade on the balance of the course. If you miss more than one exam for such reasons, you should probably withdraw from the course.

### First Midterm: Wednesday, 8 October 2008

Since we have more people than fit in either of our rooms, the midterm will be in one of the following locations:
 SB Union 226 if your SB ID number is greater than 105 900 000 Physics P112 if your SB ID number is less than 105 900 000
If you want to start the exam a little early, it will be available about 11:20 in either Union 226 or Physics P123 (sorry, we don't have P112 until 12:45).

The midterm covers chapters 1, 2, and section 3.1 of the text.
Doing and reviewing all of the homework problems prior to the exam is a very good idea. Doing additional problems from the text can be helpful. Note that homework from section 3.1 isn't due before the exam; make sure you can do problem 5 of section 3.1.

There will be five questions on the exam. One of them will be selected from the following:

• Let S be a nonempty set of real numbers. Give the defintion of the supremum of S.
• Give a definition of the set Q of rational numbers.
• State the completeness property for the reals.
• Give a careful definition of what it means when we say a sequence Xn converges to a limit L.
• Define what it means for a set to be countable or uncountable. If you use the word "denumerable", you have to define that also.

You should be able to do all the problems on this practice exam from last year. The solutions are also available, but please work the problems out for yourself before looking at them, or you won't learn anything. Here are the solutions. Here is the solutions to the midterm for Fall '07; sorry, I don't have a copy without the answers embedded.

The questions on the exam will cover roughly the same topics but will, of course, be different. Note that I didn't write these exams, so I may choose to emphasize things differently.

If you want to walk down memory lane, here is the exam, and here are the solutions.

Your grades and the grade distribution will arrive here before monday sometime.

### Second Midterm: November 24, 2008, during class time.

Have no fear, this exam will be at least as much fun as the first. The second midterm will cover the material we have covered since the first exam: primarily material from chapters 3 (on sequences) and 4 (on limits), with a little from 5.1 and 5.2 (on continuity).

Here is a the second midterm from last fall, as well as the solutions. Ours will differ a little.
Also, here is a review sheet from fall 2006 and the actual exam (which was a take-home). Again, ours will be a little different, but maybe you'll find this useful. I'm sorry, but I don't have solutions.

For our exam, I can tell you in advance what two of the questions will be:

• State what topic you will be using for your project, and give the names of the people you will be working with. Naturally, if your partners don't give an essentially compatible list, you won't get credit.
• Be able to give a complete and correct definiton of one of the following:
• State what it means for a sequence to converge to a number L.
• State what it means for a sequence to be Cauchy.
• Define a cluster point of a set A.
• State what it means to say a function has a limit L at a point c.
• State what it means to say that a function is continuous at a point c.

### Final Exam: 2-4:30 pm on Monday, 22 December 2008

The final will be cumulative, covering everything that we have done in the class.
