Homework Assignments --- Fall 2007
Directions: Please follow these directions on all homework assignments.
- On each homework assignment, place your name in the top right corner of the page.
- On the first line of the of the first page of your homework, please write down the assignment number, the pages that encompass the assignement, and list each exercise number assigned. For example, the first line of your homework might read:
Assignment #12, Page 150, #1, 3, 5, 7, 8, 10, 11, 23, 45
- If an assignment takes more than a page, please staple the pages together with a single staple in the upper left-hand corner.
- Assignments will be handed in during classtime in separate piles: the assignment #1 pile, the assignment #2 pile, etc., so please do not staple two or more assignments together.
- Simple one or two word answers or choices without explanatory prose are not acceptable. In all cases, use sound writing to justify your response.
- Read and use the following Homework Guidelines.
- Assignment #1
-
- Log onto Web Advisor and make sure that your personal information (email, etc.) is up-to-date. It is absolutely essential that your email address in Blackboard and WebAdvisor is current. Read the Syllabus, then reply to the Welcome Message in the Math 120 Discussion Board in Blackboard saying that you have completed all of these tasks.
- Assignment #2
-
- Start building your personal Math 120 Reference Book! Get a bound notebook with grid (graph) paper in it. Make a title page with your name and contact information, set up a table of contents, and begin some entries (number the pages, with page #1 being the first page with information on it, after leaving a few pages blank for the table of contents to grow into).
- Bring your Reference Book to the second class meeting on Wednesday and show me your title page, toc, and beginning page.
- Throughout the semester, you should enter important information in your Reference Book, such as definitions, procedures, key examples, explanations that make sense to you, diagrams -- ANYTHING that you anticipate will be USEFUL to you as we proceed in this course ... and beyond! This is FOR YOU. In particular, your Reference Book should serve as a very useful study guide for quizzes and exams. (Note, however, that your Reference Book is not a substitute for class notes. In general, your Reference Book should be much more concise and organized than your class notes, which normally contain everything that we do in class.)
- Each time we have an examination, I will collect your Reference Book and assign it a grade. In addition, although the final examination is closed book and closed notes, you will be allowed to use your Reference Book on the final exam.

- Assignment #13
-
- Read Section 3.1. There is a nice discussion of two examples in the reading, the first continuous, the second discrete. While you read, here are some important points to which you should give special attention:
- Scaling the axes is a bit of an art form that develops with continued experience. Don't be overly frustrated in your first attempts. There are two things to keep in mind when scaling the axes:
- Choose a scale that produces a nice-sized graph. Tiny graphs are hard to read which usually leads to errors.
- Choose a scale that makes plotting points with the given rate an easy task.
- Note that if a quantity is increasing at a constant rate, then the graph must be linear.
- Note the intuitive way that the narrative develops an equation for the model. Later in the chapter we will connect this to the form y = mx + b.
- There are no problems assigned in this section, so devote your effort to reading the examples in the section. It will pay off in the upcoming sections in the chapter.
