Message from the instructor:
Everyone is always wanting to feel that there is some practical use of the math they learn. Up to now this has been a little difficult to do. Algebra is like the support team that makes the really glitzy math possible. But again, to be able to use most of the glitzy stuff requires additional knowledge of physics, chemistry, statistics, or some such field as that. Trigonometry enables us to solve simple geometry situations, and even delve intuitively into some physical applications of math that literally reach all the way to the stars. This makes it the most easily accessible of the "glitzy" math. I think you'll really enjoy it. These examples of uses come primarily from right triangle trigonometry, which makes up part of this course. We must also, however, delve into the more formal side of trig, studying trigonometic functions. These help to make calculus and physics more powerful and useful. Although the study of trig functions may not be quite as glitzy, it ultimately yields much more fruit than right triangle trig. If you keep this in mind, this entire course should be both exciting and fascinating. kwn.

EVALUATION:

Item	Date	Discussion
3-100 point tests	Sept. 5, Oct. 3, and Nov. 7	No make up tests will be given. A missed test will be replaced by 1/2 of your final exam score.
1-200 point Final Exam	Dec. 12	Final will be comprehensive.
Online homework- 100 points	Discuss

GRADES:

The accumulative total for the course will be 600 plus a few points, depending on miscellaneous assignments, and your accumulative total will be divided by that amount to calculate your final average.

90 - 100 = A, 80 - 89 = B, 70 - 79 = C, 60 - 69 = D, 0 - 59 = F

NOTES:
l. Final percentage will be rounded UP, i.e., a final percent of 79.00000001 will be rounded up to 80.
2. You should keep all returned papers. You should also keep track of the ratio (your accumulative total)/(The accumulative total possible to date) as the quarter progresses. If this ratio is below 70 at midterm, you should come for a conference with the instructor to discuss what each of us can do to retrieve you from doom.
3. If you have more than two excused absences you will be dropped from the course, as required by the college admission policies.

4. Words of wisdom regarding Math homework.

I hear........ and I forget,
I see..........and I remember,
I do...........and I understand.
