Systems of Linear Equations (part 2)

Today we had a short quiz on the equations of circles and our new distance formula. We reviewed how to complete the square to find the center and radius of a circle on the cartesian plane. I demonstrated how to complete a question such as number six from lesson three, and then moved on to discuss the homework.

I demonstrated number four (b) from lesson 5, and gave some tips for number 5 from the same lesson. We'll be quizzing a couple of times this week so be sure to ask questions as they come up.

Lesson 2 #5...good question!

Around in circles...with groups!

Don't forget that if you get stuck you can always pick up an old final exam and do some studying. The links are on the right...and ask some questions by commenting below.

An Icy Pre-Calc Class

Sorry this is a bit late but I thought I'd post a few of the words we had on Thursday.

Circles Everywhere...

Today in Pre-Calc we took a look at Arcs and their corresponding central and inscribed angles. We also spent some time looking at Cyclic Quadrilaterals. The language sounds pretty tough...but the math isn't too bad. I also mentioned that we'll be quizzing Lesson 2 tomorrow. Good luck with the studying.

Some circle stuff for you

Here are the slides for the last couple of classes. Please do your best to have lesson 2 finished for tomorrow.
