We started a new chapter today -- coordinate geometry. We are skipping ahead to chapter 13 and we will return to pick up the other chapters during the next semester.
Our topic today was how to use the distance formula in working with straight sided figures and circles. We used the pythagorean theorem to find the distance formula, and then we also showed how the formula of a circle can be found. We practiced with both types of problems before getting started on the assignment.
Assignment: section 13-1; page 526-527; WE 5-12; 17-25
