We continued our work with coordinate geometry today by taking a look at vectors---what they are and how you can calculate with them. We illustrated how vectors are used in navigation on maps/etc. first. We then went over how to determine the slope, magnitude (length), and sum of vectors in various types of problems. We went over 4-5 examples together before getting started on the assignment.
Assignment: section 13-4; page 541-542; WE #1-25
