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.

Differential Equations,. is an equation, in which one or more variables, one or more functions of these variables, and also the derivatives of these functions with respect to these variables occur. The . of a differential equation is equal to the order of the highest occurring derivative.

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.
