Our big picture goal to.day was to gain fluency with application of trigonometric ratios while understanding why we do what we do to find unknowns. The new content: using inverse ratios to find acute angles of right triangles; interpreting angle of elevation or depression to solve real-world applications of trigonometric ratios.

The textbook is excellent. Read pp 620-624 and 628 for assistance.

We did a warm-up with completing the square to find the standard form equation of a circle, as well as p 625: 22.

After we learned about inverse ratios (switch input and output to find angles) we applied them by doing 10-13, 17, and 19 on p 625.

We had a 4 pt homework quiz over HW #11 at the end of class.

Homework #12 (due next block) - pp 628-9: 1-3, 5-6, 8-16. On the first 5, be sure to make a good sketch.

Unit Review (HW #13) not due until Wed-Thurs next week:

pp 496-7: 1-8, 13-15, 18, 23, 25; p 659-60: 1-9, 13-16.

THERE WILL BE A SHORT QUIZ ON MONDAY -TUESDAY. About 10 pts or 12.

One distance formula problem, one equation of a circle problem, 2 trig problems (one like 7-9, one like 14-19 on p 625).
