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 Trig Syllabus

Advanced Algebra/Trigonometry is a course that covers trigonometry and advanced topics in algebra (such as matrices and conic sections). The honors section of this course will go into greater depth in these areas through increased emphasis on theory and application to real-world problems and will incorporate material tangentially important to the subject such as set theory and advanced geometry.

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. Tests will be graded on a 100 point scale, quizzes 50, and homework and other projects at the teacher’s discretion. A quiz or test will be given at least once a week, though frequently they will be given more often (especially quizzes).

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. As this class is being taught first period, you should have no trouble accomplishing this. Remember: four tardies to first period results in detention as per school policy.

This class has a class blog at htrigfall07.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.
