Okay so today was our pre-test.

We got into groups and worked together on the questions.

Mmmm the test was alright, I'm glad we got to work with other people because I was honestly stuck on a few questions.

Here's a little review:

Let's say vector a is going 6 cm east of west and turns 90 degrees south. That vector, b, is 10 cm south of north. It's tip-to-tail so we have to use the triangle method. We need to find the resultant, which is the missing vector that connects to vectors a & b, creating a triangle.
Since one of the angles is 90 degrees, we can use the pythagorean theorem. a(squared)+b(squared)=c(squared)

The resultant vector equals 11.66cm.

Don't forget how to use trisolv2 on your graphing calculators. It really helps me.

Well our test is tomorrow..actually very study and good luck=)
(sorry for the late scribe)

The next scribe can be Lamael(:
