generic class FunctionTanCuPnt from GccIter (

    TheCurveTool as any ) 

inherits FunctionWithDerivative from math
         
    ---Purpose: This abstract class describes a Function of 1 Variable 
    --          used to find a line tangent to a curve and passing 
    --          through a point.

    ---Purpose: Computes the value of the function F for the variable X.
