We added time to our equations of lines.

Reminder about vector notation in Brown

I want to remind everyone that Brown uses the unfortunate
vector notation of (x, y) instead of the preferred <x, y>.
Forewarned is forearmed when doing your homework.

Reviewing Vectors

Today we had a worksheet that forced you to remember what you
have forgotten about vectors. Make sure you finish this worksheet.

Tonight's HW: Brown p.436-437/17,18,23 and Demana p.490/57

Vectors until Vacation

Valentine's Day is spent discovering the Dot Product.
The rest of the week is spent writing proofs three ways (in groups).

2/14 HW Brown pp.444-445/1-19 odd, 23, 27-29
2/15 HW Work more on worksheet proofs (don't let your group down!)
2/17 HW Enjoy vacation and get rest.

More with vectors

Today we looked at the connections between coordinate,
geometric and vector proofs. The classwork and homework
make you think more about vectors in algebraic and geometric
ways. Remember that you are responsible for the classwork
as well as the homework.

Intro to Vectors

Today we delved into vectors (section 6.1 of Demana,
section 12.1 of Brown) via an activity and summary document
(see the document folder in our conference).

Finishing up the identities for Tuesday's test

Make sure you know how to derive the various identities, particularly
the sum and difference identities (your homework is to be able to generate
the three different proofs we went through).
