Trig Identities

Lots of Proofs this unit! We start with simplifying practice and then jump in.

Note: We will be using the Demana book for most, but not all, of the assignments.

The plan until the test of Geometric Trig

You will be working through the following Mixed Trig problems, in class and at home, and then we will have a test.

Mixed Trig Problems: p.356-358/11,14,18,21,24,25,29-35,37-40,42

You also need to do the Hero's Formula derivation.

The Geometric Trig test will have questions that require a full understanding of the trig area formula, the Law of Sines, and the Law of Cosines. There will be one problem (chosen by me) from the "C" problems on page 358. I have not assigned every problem in the unit but notice that after you finish these problems you should be able to find the area, the sides, the angles, the length of the median/angle bisector/altitude, and the radii of the inscribed and circumscribed circles for any triangle - among other things.

2/09 Test for E-Block
2/10 Test for G-Block

We may have to change the dates of the test for various reasons (weather, lack of progress on the problems, other unforeseen difficulties) but that is what we are aiming for.

Homework on the snow day

Sorry but we are behind the other Honors Advanced Math classes and these problems are just continuations of what we were doing before (no instruction necessary!). This will also bring both classes into alignment for the schedule.

9.1, 9.4  Mixed Trig Problems
            HW p.337-338/31-33, 37  and  p.356-358/11,14,18,21,24,25,29,34
