Matrices

Now we learn how to deal with lots of information at once. There are many applications of matrices that are not covered in our text so we will be exploring some of them via worksheet. Make sure you bring your calculator every day!

The last day this week you will work through a packet reviewing exponential properties.

An introduction to the mathematics of 3D

We will be moving into chapter 4 which studies matrices - a technique that allows us to handle huge amounts of data. 3D makes a great bridge topic between systems of equations and matrices. Remember, this is only an introduction. You do not have to be an expert! That comes in two years. ;-)

Day 1: Representing 3D with points, equations of planes, graphs.
Day 2: Solving systems of equations in 3D - there are many possible outcomes. (Answer Key)

The homework both days is to finish the handouts.
