 Read all but the proofs of sections 15.3 and 15.4.  (We will do the proofs in class, as usual.)From 15.3, do 1-3, 5-7, which is review of previously studied ideas.From 15.4, do 2-4, which apply Theorem 15.3.

 MAP testing is this week, causing chaos in Proof Geometry because students are spread among three levels of English.  Therefore, in class we willdo the "Programming with Trigonometry" lab two days;review trigonometry two days;and take the math MAP test the other day.(The two sections of PG are on different schedules.)Next Monday and Tuesday, we will have a comprehensive assessment on trigonometry, which we have studied for six weeks.  Monday's portion will be straightforward computations like the drills we've been doing in class.Tuesday's portion will be more conceptual: applications of trigonometry to measurement (as in 17.2), proving identities, polar coordinates, the complex plane.Therefore, this week's homework is to redo previous homework assignments and to go through class notes; identify areas of weaknesses and work on them; come to the review days in class ready to ask questions; and attend office hours if necessary.Review questions from class (part 1):

 From the Chapter 17 Review, do 11-15.

 From 17.8, do 24, 25, 30.  Finding all the solutions for 25 requires recalling some algebra skills (e.g., if xy = 0, then x = 0 or y = 0, right?)From the Chapter 17 Review, do 6, 8, and 10.

 From 17.8, do 16, 17, 21-23.  For 23, look for appropriate substitutions from the theorems.  While challenging, it is possible to find an algebraic expression over sin(Theta).
