Public Member Functions
	Expr_FunctionDerivative (const Handle< Expr_GeneralFunction > &func, const Handle< Expr_NamedUnknown > &withX, const Standard_Integer deg)
	Creates a FunctionDerivative of degree <deg> relative to the <withX> variable. Raises OutOfRange if <deg> lower or equal to zero.
Standard_Integer	NbOfVariables () const
	Returns the number of variables of <me>.
Handle_Expr_NamedUnknown	Variable (const Standard_Integer index) const
	Returns the variable denoted by <index> in <me>. Raises OutOfRange if <index> greater than NbOfVariables of <me>.
Standard_Real	Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &values) const
	Computes the value of <me> with the given variables. Raises DimensionMismatch if Length(vars) is different from Length(values).
Handle_Expr_GeneralFunction	Copy () const
	Returns a copy of <me> with the same form.
Handle_Expr_GeneralFunction	Derivative (const Handle< Expr_NamedUnknown > &var) const
	Returns Derivative of <me> for variable .
Handle_Expr_GeneralFunction	Derivative (const Handle< Expr_NamedUnknown > &var, const Standard_Integer deg) const
	Returns Derivative of <me> for variable with degree <deg>.
Standard_Boolean	IsIdentical (const Handle< Expr_GeneralFunction > &func) const
	Tests if <me> and <func> are similar functions (same name and same used expression).
Standard_Boolean	IsLinearOnVariable (const Standard_Integer index) const
	Tests if <me> is linear on variable on range <index>
Handle_Expr_GeneralFunction	Function () const
	Returns the function of which <me> is the derivative.
Standard_Integer	Degree () const
	Returns the degree of derivation of <me>.
Handle_Expr_NamedUnknown	DerivVariable () const
	Returns the derivation variable of <me>.
TCollection_AsciiString	GetStringName () const
Handle_Expr_GeneralExpression	Expression () const
void	UpdateExpression ()
