Exam Information for Math 141

Fall 2010

As it says on the course syllabus, there are two midterms and a final in MAT141, which count for 25%, 25%, and 30% 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: during class on Monday, October 18, 2010

The midterm covers Chapter 1, 2, and some of chapter 3 in the text.
Doing all of the homework problems prior to the exam is a very good idea. Doing additional problems from the text can be helpful.

For the exam, make sure that you know

If you wish to use a calculator on the exam you may, although it is by no means necessary and unlikely to be of any help: all problems may be readily done without one.

To give you some idea of what to expect, here is the first exam from last year. Keep in mind, however, that I didn't write this exam, so the format and choice of problems will certainly differ. In addition, their exam was a bit earlier and they hadn't yet covered any of chapter 3. Also, problem 6 uses the series definition for

ex = 1 + x + x2/2 + x3/3! + x4/4! + ...,

which we didn't discuss. Still, this is better than nothing.
Here are the solutions to last year's exam. Please make a serious attempt at the exam before looking at them!

Al will be holding a review session on thursday evening at 5:30. Go to the 3rd floor of the SAC around 5:15, and he will find a nearby room. Also, I will review in class on friday.

Results: While the exam had some challenging problems (especially 5d and 2b, which were meant to be hard), I was a bit surprised at how much trouble some people had with problems 1 and 3, and also 5a. Oh well. Note that if you got a C (or even an F) on the test, you can still recover from it and do well in the course. But you will have to make some real changes.

Second Midterm: in class on Wednesday, November 17, 2010

The second midterm will cover the material we have covered since the first exam, specifically material from chapters 3 and 4. As on the previous exam, you should expect to be asked to give some definitions or state some theorems precisely, do a proof or two, and do a few problems that are more calculational in nature.

The second midterm from last fall is available; you should be able to do all of the problems. Keep in mind, however, that we will have covered a bit more material (particularly sections 4.6 and 4.7), and some of the material on their exam was covered on our first midterm. Here are the solutions, but please attempt the problems before consulting them.

For the exam, make sure that you know

As on the first midterm, a calculator is allowed but almost certainly of little use.

Results: Here is the exam, and here are the solutions.

Some people did reasonably on this exam, but a few did very, very poorly. Quite a few made some disturbing mistakes, like not knowing the chain rule. These people need to focus more on fundamentals as well as the theory.

Final Exam: 11:15am on Monday, December 13, 2010

The final will be cumulative, covering everything that we have done in the class. However, extra emphasis will be on material since the second midterm, specifically that on integration (chapter 5).

Half of the final will be MAT131-style problems. If you can do well on these, you will get at least a B in the course. If you cannot do well on these, don't expect a decent grade, no matter how many theorems you can prove.

As agreed to in class, the first half of the final will be in-class on wednesday, Dec 8. To help you get an idea of what is on a MAT131 final, here are a couple of old ones:

If you got at least 85 (out of 124) on part 1 of the final, you are guaranteed a grade of at least B in the course. If you got below 85, you should plan to redo another version of part 1 during the final period on monday.
There will also be a second part of the final on monday: people who got over 100 points on part 1 should only do part 2 (your grade on part 1 is sufficient), and if you got between 85 and 100, you MAY do part 1 over, but you don't have to. Indeed, I recommend that in most cases you should focus on part 2.
As mentioned, part 2 will have 4-5 definitions or statements of major theorems, a proof by induction, and 2-4 other proofs.
