UNIT Q AND R - important info and answers to questions

**WHEN IN DOUBT, GO BACK TO YOUR SSS AND THE VIDEO LESSONS!  THERE ARE EXAMPLES OF EVERY TYPE OF PROBLEM ON THE TEST AND IT WILL SHOW YOU HOW YOUR ANSWERS SHOULD BE FORMATTED AND EVERYTHING...***

(If anything, this test is showing me exactly WHO is not paying attention to the videos or completing PQ's... but in the end, it's YOUR responsibility...)

Notes/changes from Mrs. Kirch and questions from classmates that I am sharing the answers with for everyone...

In general

• Answers for test always go in GREY BOXES.
• You still must show step by step work when you copy from your scratch paper to your "final draft" test.  Don't leave anything out, just make it nice, neat, and readable.
• If you need more boxes on any of the identity proofs, please neatly divide the box(es) in half for how many you need.  Count your steps on your scratch paper before copying on your "final draft" test.
• Utilize answer bank for Unit Q Concept 1 & 5 problems. (in previous post)

Unit Q

• In general:
• Q:  do you want pi radians or decimal radians for unit Q? 
• A: If the degree is an exact degree, then the radians should be exact radians (with pi). If the degree is a rounded degree, then the radians should be decimals (no pi)
  example:
  120 degrees should be 2pi/3, not some crazy decimal
  122.7degrees should NOT have a pi in the final answer
• #6
• Q: For #6, is the radical 9x^2+4 supposed to equal to something?
• A: No, you just have to simplify it using the information given. Compare to your SSS problems - it's very similar.
• #8 - utilize the same process as Unit O Concept 2 when deciding how to write and round your answers in both degrees and radians
• #9
• Q: is the (2 theta) a typo? Or is the 2 suppose to be there?
• A: it is Cosine of 2 Theta. The 2 is supposed to be there.
• #10
• Q: is the theta suppose to be over 2 or is it suppose to be tan theta?
• A: it is Tangent of Theta divided by 2.
• #16 - only has TWO answers (cross off the last blank for both degrees and radians)

Unit R

• #31-33 
• Q: For Unit R #31-33. Do we just input them into the calculator or something?
• A: All directions are the same as the problems in the SSS that match up to that concept - Use the examples from your SSS and the video lessons so you know what to do. You should have done a lot of practice in your SSS and on the PQs on those exact problems for Concept 1.
• #32 - 
• Q: Do I have to convert to degrees?
• A: You can, but your final answer should match up to how the problem was given
• #33 - 
• Q: I don't see that formula anywhere.  What am I supposed to do?
• A: With a little algebra, you can manipulate it.  Be careful! 
• #34-35 - make sure to check your final answers in your calculator and compare the decimals to make sure they are identical.  If they are not, then go back and check your work. 
• #35. You must use SUM FORMULA to solve. It says so on the actual problem, but on page 2 instructions it says to use difference.  That is a typo.  You MUST USE A SUM FORMULA.
• #38 - it is acceptable to leave a radical in the denominator of your final answer.
• #41-46 - in the "identity/step used", you can simply write "expanded with sine sum formula" (or whatever you expanded with...) if you don't want to write out the entire identity.
