For Investment Geometric Problems

Abstract

Solving geometric problems of special importance is the transformation of a plane called inversion. When solving geometric problems, the transformation of the plane called inversion is of special importance. An inversion is a mapping of a plane that a set of directions and a circle maps to the same set, and in doing so it can map a line either to a line or to a circle, and it can also map a circle to either a line or a circle.
