Challenge problem #1

1. Explain why the cyclic group {0, 1, 2, ..., n-1} is closed under addition mod n and multiplication mod n.

2. Research groups, rings, and fields (try wikipedia). Explain why a cyclic group using mod n is a field if n is prime (and why it isn't if n isn't prime).

Quiz Tomorrow

The following will be on the quiz:

Math:
Writing linear functions
Evaluating linear functions
Finding inverses
Verifying inverses
Direct variation

Theory:
Closure
Identifying functions (in multiple contexts)
1-to-1 and onto

Find (f+g)(x), (f-g)(x), (f*g)(x), (f/g)(x), (fog)(x), and (gof)(x) for each set of functions.

1. f(x) = 3x+2
g(x) = x^2 (x squared)

2. f(x) = x-5
g(x) = -2x+10

Homework 8/10

Your homework is to complete the handout on sets and closure and to be ready for a homework quiz on monday.

Commenting on Posts

The way this blog is currently set up, comments are only permitted by registered users. If you want to comment on a post you will need to sign in or, if you have not commented before, register a blogger id (if you have a google id, you can use it to sign in to blogger). The website should be able to walk you through this process. When registering you will be asked what name you would like to appear on your comments: set up your account so that the name appearing on your comments is your first and last name. Any anonymous or pseudonymous comments will be deleted. As detailed in the syllabus, no comments will be allowed that disparage other students or give complete solutions to homework. Since this blog is associated with Southeast, any violations of the commenting policy will be subject to school discipline. I would encourage everyone reading this post to leave a comment (something as simple as asdf or n/t will suffice) in order to make sure that you understand how to do so.

Honors Algebra II Syllabus

Honors Algebra II covers intermediate and advanced algebraic topics, mostly dealing with various types of functions. As this is an honors class, we will be covering these topics at a more abstract and theoretical level than the cp version of this class as well as covering topics at a faster rate. In addition, to better prepare you for future advanced math classes we will be working on developing your mathematical reasoning ability. Often this will take the form of written assignments and/or proofs. Almost every test and quiz will include at least one proof similar to those we have covered in class so it will behoove you to pay close attention to such proofs and keep notes over them. Remember: when writing proofs, generally the more written explanation you provide, the better your proof will be.

Students will be graded on daily work, homework, quizzes, tests, and/or projects. Students are responsible for doing the work assigned to them and for reading any supplementary texts assigned. Test and project grades will comprise 40% of the final grade, quizzes 40%, and homework/daily work 20%.

Students are expected to come prepared for class. This means you should have paper, pen or pencil, and your book. If you find that you do not have one of these items, you should make arrangements to acquire them before the bell rings. Students who are unprepared once class has started more than once in a week may be docked points from their daily grades. Students should be ready to work when the bell rings. This does not mean that you can run in when the bell rings, lay down your things and go to the restroom. If you plan on using the restroom, be sure to give yourself enough time to get to class before the bell. Remember: a tardy results in detention as per school policy.

This class has a class blog at halg2fall07.blogspot.com. All homework for the class will be posted on the blog. In addition challenge problems will be posted on the blog periodically. Students are encouraged to use the comments on blog posts to discuss problems and help their fellow students. Rules for posting comments are as follows:

1. All students must post under the name they use in class (no anonymous comments).

2. No disparaging comments are to be made about other students or their work.

3. While you are encouraged to help your classmates with their work, you may not simply post the solutions to the problems. You need to help each other, not do each others work.
