| CONIC
SECTIONS |
|
The simplest curve of the four
conic sections is the circle. A circle is the
set of all points in a plane such that the distance from a fixed point
(the center) is a constant
(the radius). The standard equation of a circle with center
(h, k) and radius r (r >0) is:
(x - h)2 + (y - k)2 = r2
Let’s write the equation for the circle
that has center (3, -2) and radius 6.
