...so. You got a reading in your box this afternoon. Its a couple of pages long and could be a little intimidating.
your mission:
* extract knowledge that will allow you to try the problems set forth for homework
* try the questions and see how far you get
* find other sources of informationto help you get there (the internet: trigonometric identities)
* bring this sheet to class with questions and concerns. we will be working through the rest of the information together.
the fundamental realtionships at the bottom of 120 are important, as are those on the top of page 122.
HOMEWORK: read 120-122. p 122, 1-35 odd (all answers below). read page 127.
ANSWERS TO THE HOMEWORK:
You may use these at any time--it is more important to understand WHY they are the answers as opposed to just glancing at them.
1. ctn θ --NOTE: in current books, cotangent is usually denoted as cot θ as opposed to ctn θ. If I slip up, sorry.
3. csc θ
5. sin θ
7. sin^2 θ (this is sin squared of theta)
9. csc^2 θ
11. 1
13. 1
15. cos θ
