You will be submitting 5 identity proofs. You have SOME choice about which ones though!
Your 5 must come from the examples indicated in the grid below, all of which come from Visions 2 and Carousel 2. Your mark depends not only on the correctness of your proof, but on the level of difficulty of the examples you choose. For example, if you choose 5 hard ones, and you do them all perfectly (see below for what I mean by “perfectly”), then you’ll get 100%. If you do 5 medium ones perfectly, you’ll get 85%. Note that there are only 4 easy ones, so nobody can just do all easy ones. Oh yeah, that’s right, I’m way ahead of you.
So…what do I mean by perfect?
- Correct procedure:
- one side is simplified at a time
- each line shows one step only
- each line is justified with a trig identity or an algebraic procedure
- QED, baby!
- Correct math, of course
Also note that if you do MORE than 5, I’ll mark the best 5. You should also know that there are some here that I actually have not been able to figure out how to prove. YAY! Maybe one of you will put me out of my misery!
