How can we place circles in the coordinate plane?
Read pp. 695-697 in the text book (section 12-5). Do questions p. 697 # 1-12, 16-18, 28-34. No work is needed for #1–8, 28–32.
The focus of today's lesson is connecting the equation of a circle with circles on the coordinate plane. We discussed how the circle equation is dervied from the distance formula. The equation: (x-h)^2 + (y-k)^2 = r^2 can be used to describe a circle centered at (h,k) with radius, r.
