Today we are writing our last unit exam in Pure Math 20. Now begins the process of reviewing for the final exam. This blog can be an excellent resource for your review. Remember that you can go back to the beginning of the semester on the blog and look at the links and information I have provided. If you are having difficulty in a unit while you are studying and reviewing for the final exam you can use the resources here to assist you.

Oh yeah, do not forget to tell your friends in the class to go to the blog. Many of them do not visit the blog as regularly as you do.

Happy studying!!!!!

### Equations of Circles

On Thursday we studied how to determine the equation of a circle. The following link let's you practice this some more.

The picture I have included is of a crop circle in a farmer's field outside of Drayton Valley, Alberta. How would we determine the coordinates of the center of this circle if we wanted to write its equation?

Hint: It has something to do with a piece of technology that starts with a G!!!
