Law Of Cosines: Cosine Law

When to Use it?

The above chart shows how to use cosin

e law to solv

e for

different things: (IE) the box on the top left side formula solves for a(side), the one below it for b(side) and the one below that for c(side). Across the table is the corresponding formulas for angles A, B, and C.

Scenario 1 (of 2) triangle shows that a (side) = 13, c (side) = 20) and B (angle) = 103(degrees) and are looking to find b (side).

Scenario 2 (of 2) shows finding the angle A

Similar triangles – they have the same shapes but different lengths(or distances)

Summary : Use the law of cosines if you have Two Sides and the Included Angle, OR All Three Sides.

"The inverse cosine of the cosine is the angle itself."

Today we finalized our objectives that each of us are responsible for, and the criteria was set on how we are going to be scored. Each of us has an objective to learn and perfect so that they can teach the class how to do that specific objective, by putting it on our new class wiki http://www.grade11appliedmath.wikispaces.com/. Tuesday first 9 objectives are due Tuesday November,16/2010

Instead of me boring everyone who knows this...

"What would you tell someone (and there are currently about 10 students), in your class, who had absolutely no experience with Accelerated Math?"

Respond specifically to these questions:

1. What are the pros, re: A/M?

2. What are the cons, re: A/M?

3. What advice would you give new students?

4. If you are a new student, what do you need to know that you haven't yet figured out?

5. What do you wish you had done differently in the past, with regard to A/M?

6. What can I do better as your teacher to prepare you/your class to be successful in this course?

I look forward to reading your responses.

Work period, September 27/2010

Today we had a period to work on our accelerated math, and a review page to help us prepare for our upcoming test. Mr.Maks gave us an analogy today...if your on a escalator and its loses power don't stand around and call for help, take charge and climb the stairs (do the work.)

Check this out. Awesome math glossary.
