Geometry,. and . are not defined in today’s mathematics. We determine the relations between them only by axioms. We can imagine a . as a trace of a point moving in a plane along the shortest route between two different points without changing its direction.

Function Theory,Analogously to real functions, we can assign complex values to complex values, i.e., to the value . we can assign a complex number ., where . and . are real functions of two real variables. We then write .. The function . is a mapping from the complex . plane to the complex . plane.
