generic class FunctionTanCuPnt from GccIter (
TheCurve as any ;
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.
uses Pnt2d from gp
is
Create (C : TheCurve ;
Point : Pnt2d from gp ) returns FunctionTanCuPnt from GccIter;
Value (me : in out ;
X : Real ;
F : out Real ) returns Boolean;
---Purpose: Computes the value of the function F for the variable X.
-- It returns True if the computation is successfully done,
-- False otherwise.
Derivative (me : in out ;
X : Real ;
Deriv : out Real ) returns Boolean;
---Purpose: Computes the derivative of the function F for the variable X.
-- It returns True if the computation is successfully done,
-- False otherwise.
Values (me : in out ;
X : Real ;
