What is the standard form of an equation of a circle with center (0, 0)? Use the Distance Formula to find an equation of a circle with center (0, 0) and radius r. Let (x, y) be any point on the circle. Then the radius r is the distance from (0, 0) to (x, y). d = 2(x2-x1)2 + (y2-y1)2 Distance Formula

The stereographic projection relates to the plane inversion in a simple way. Let P and Q be two points on the sphere with projections P ′ and Q ′ on the plane. Then P ′ and Q ′ are inversive images of each other in the image of the equatorial circle if and only if P and Q are reflections of each other in the equatorial plane.. In other words, if: P is a point on the sphere, but not a ...
