-Create (Curve : Curve from Geom2dAdaptor ;
- Dir : Dir2d from gp ) returns FunctionTanObl from Geom2dGcc;
-
-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.
