¹Hint: produce a sketch first*
68 Tues Dec 11 7.6 Solving Quadratic Trigonometric Equations pg. 436-437 #4d¹, 5c¹, 6b¹c¹, 7a¹, 7e, 8d¹, 8f¹, 9d¹, 14, 17
¹ = no rounding!!!
69 Wed Dec 12 Review Day 1 pg. 440 #2, 3d, 4a, 5ab, 6a, 8¹, 9¹, 10b, 12abc² DO 12 c LAST.

¹as usual, set up LS/RS separately

²for 12c, although using the quadratic formula yields the solution, the final simplification process is difficult. Instead, expand the LS, then “factor by grouping.”
