Hi, I am Cathy, your teacher for this course. Welcome to Trigonometry.
Trigonometry is an advanced math course. **It is required that you have taken Algebra 1, Geometry, and Algebra 2 before you take this course.** It will be assumed that you have working knowledge from these courses. Trigonometry is a half-credit course.
It is a required part of this course for work to be shown on ALL revisions. I will request it if you do not show it. I will not give you credit for a lesson that requires revisions if work or explanation is not given. In addition, there is a general rule that if a student gets 3 or fewer problems incorrect on the first submission, then the student may move on to the next lesson. This is only valid FOR THE FIRST SUBMISSION. Once revisions are required, I will ask for work to be shown for whatever problems I deem necessary to prove mastery of the concepts presented.
It is very important that you do all of the lessons in order. Each lesson builds upon the next, so don't begin a new lesson until you have completed all previous lessons. In this course when there is a multiple choice assignment you will get an immediate response. After you submit a multiple choice assignment go directly to your student desk and file cabinet. Please follow the instructions of the teacher. Do not move on to the next lesson if you are told to STOP and show your work. Only move on to the next lesson when a lesson has been graded.
Some special characters have text-only counterparts if you need them. You should, however, be able to either enter the special character from the toolbar or copy and paste it into the text box from the lesson. If for some reason that is not possible, here's a short list of symbols you should be familiar with:

If you need help, ask for help. Be specific with your questions and what you don't understand. I will try a little harder to explain myself. If you have any questions, don't hesitate to contact me using the form at the bottom of the page.
**I do not answer lessons on Sunday, anything submitted that would get a reply on Sunday will get a reply on Monday. |
