Here is the final exam review with the solutions.
12/04/2007
- I've scheduled the final exam review. It will be held in ANS 0408 on December 11 from 5 - 7pm. It will be impossible for me to cover the material as I have in the previous reviews, as neither you nor I would like to take part in a 9 hour review. So it will be up to you to make the review productive. Please look over old quizzes, exams, reviews and WebAssigns. Figure out what confuses you and what you've forgot and come with plenty of questions to ask. This review won't work if you guys come unprepared. See you there!
11/27/2007
- Here are the final answers for the exam review.
11/26/2007
- The exam review will be on the 27th from 5 pm until 7 pm in ANS 0408. The written review can be found here.
11/09/2007
- I will be holding extended office hours Monday, November 12th. I will be available to answer questions from 11 am until 1:30 pm in my office, MTH 3303.
- I have posted a take-home quiz below in the quizzes section. Please follow all of the directions on the top of the quiz. The take-home will be due at the beginning of recitation next Friday.

Here is a list of helpful problems in the textbook.
- 11.3
  (in the solutions manual): 1, 7, 13, 19, 37
  (other good problems): 7, 8, 10, 14, 15, 16, 36, 38
- 11.4
  (in the solutions manual): 1, 7, 13, 25
  (other good problems): 2, 3, 6, 9, 11, 21, 23
- 11.5
  (in the solutions manual): 1, 7, 13, 19, 37
  (other good ones): 2 - 6, 8 - 12, 21, 35, 36, 38 - 40
11/01/2007
- I would like you guys to see that the types of functions and subsequent analysis that are presented in this class actually are important to the various fields that you study, regardless of whether or not you will directly use them during your career. In order to facilitate that and to give you guys an "easy" quiz grade, I am assigning a small task (with Justin's approval) that will count as a quiz grade. Everyone needs to find some article from a newspaper, scholarly journal or magazine (note: websites don't count - but you can use something like wikipedia to find the article) which relates somehow to what we have been studying this semester.
  
  For example, if you want to find an article that deals with exponential and/or logistic growth, you could look for something in biology (bacterial growth, spread of viruses, responses to stimuli), computer science (Moore's Law), economics (rule of 72), psychology (sigmoid function), etc. Also, trigonometric ratios are used in modern dance, architecture and other areas.
  
  The assignment:
  You need to submit a hard copy of an article to me by class on December 7th. The article must relate to one of the following subjects:
  - Exponential growth
  - Logistic functions/growth
  - Present value of investment
  - Trigonometry/geometry of angles
  - Optimization of functions
  - Other applications of integraton and/or derivation
  - Differential equations
  - Taylor polynomials / infinite series
  - Normal, exponential, Poisson and/or geometric random variables (from probability - we will be studying them it soon)
  The article must originate from one of:
  - Scholarly journal
  - Magazine
  - Newspaper
  The following are NOT acceptable sources (although you can use them to find good sources):
  - Webpages, including Wikipedia
  - Textbooks
  Only one student may submit any particular article; that is, Suzy and Bob can't both submit article x. To prevent this from happening, you will need to email me in order to "claim" an article. If it is already taken, then I will alert you to this, and you will need to find another one. Thus, the earlier you claim an article, the easier things will be for you.
- Someone has asked me to give practice problems that may be helpful in preparation for the quiz. I am going to try to give problems every week and in the future will try to get them out earlier in the week. These will not be due for a grade. The following problems should be helpful and also are in the solutions manual. I would suggest trying the problems first before looking at the manual. p. 560: 1, 7, 13, 19, 25 and p. 567: 1, 7, 19 Some other problems to do (these aren't in the solution manual) p. 560: 2 - 6, 8, 14, 17, 18 and p. 567: 2 - 6, 8, 11, 12, 14

09/17/2007
- I will be holding a review from 5pm until 7pm, tomorrow, Tuesday evening. The review will now be held in Physics room 1412. This room will be large enough to hold everyone.
- Also, you can pick up your graded quiz 2 at the review or during my office hour on Wednesday.
09/14/2007
- I will only offer make-ups under the following documented circumstances:
  1. Religious holiday - Notice should be given at least one day in advance.
  2. Death in the family
  3. Extreme illness
  4. Pre-existing doctors appointment - This case covers appointments that were made before the semester started. I need to be notified *now* about such an appointment.
  5. Court date - Notice should be given at least one day in advance.
  With the exception of reason (1), all of these have documentation which you will need to provide to me in order to receive a make-up.
  I will be dropping at least 3 of the lowest quiz grades. Any other missed quizzes will be covered by those dropped grades.
09/11/2007
- The quiz was a bit too long. This week's quiz will be shorter.
- If you are Jewish and will be missing the quiz this Friday because of Rosh Hashanah, please notify me before Friday so that we can schedule a make up. I will only be writing one make up quiz, so everyone will need to take the make up at around the same time.
09/06/2007
- Don't forget there will be a quiz tomorrow covering sections 8.1 - 8.4. You will also have 3 WebAssigns due Tuesday morning. If you have any questions, you should bring a print out of the WebAssign to class.

- We will have class this Friday. We will be meeting at 3 pm in Mth 1313. I will be giving a review of material covered in 220, as well as answering any questions that you may have about the WebAssign assignments.
08/28/2007
- Welcome to the class.
- In the past I have emailed my students at least once and week and whenever something important comes up. If you rarely check your @umd.edu email address, then you should change your contact email so that I can get ahold of you. To change your contact email, simply visit this site and follow the directions.

Web Assign Login Page - note that it is different from last year's page
Web Assign Directions
You will need to eventually purchase an ancess code for Web Assign. It costs about $12. You may use Web Assign for free for 2 weeks. It is VERY IMPORTANT that you do not purchase an access code before you are 100% certain that you will remain in the exact same section. If you drop the class, you will not get a refund, and if you change sections, you will need to purchase a new access code.
If you have any questions about your Web Assign homework, please print it up and bring it to discussion.

Quizzes

You may not use any type of calculator when taking a quiz. This will help you practice for the exams. Trust me when I say this is to your advantage.
Quizzes will be given at the end of every discussion, except the ones held the days after the first and second exams.
