22 class Cosine from Expr
24 inherits UnaryExpression from Expr
26 uses GeneralExpression from Expr,
27 AsciiString from TCollection,
28 Array1OfNamedUnknown from Expr,
29 Array1OfReal from TColStd,
30 NamedUnknown from Expr
32 raises NumericError from Standard,
33 NotEvaluable from Expr
37 Create(Exp : GeneralExpression)
38 ---Purpose: Creates the cosine of Exp
39 returns mutable Cosine;
42 ---Purpose: Returns a GeneralExpression after a simplification
43 -- of the arguments of <me>.
44 returns any GeneralExpression
48 ---Purpose: Returns a copy of <me> having the same unknowns and functions.
49 returns mutable like me;
51 IsIdentical(me; Other : GeneralExpression)
52 ---Purpose: Tests if <me> and <Other> define the same expression.
53 -- This method does not include any simplification before
60 Derivative(me; X : NamedUnknown)
61 ---Purpose: Returns the derivative on <X> unknown of <me>
62 returns any GeneralExpression;
64 Evaluate(me; vars : Array1OfNamedUnknown; vals : Array1OfReal)
65 ---Purpose: Returns the value of <me> (as a Real) by
66 -- replacement of <vars> by <vals>.
67 -- Raises NotEvaluable if <me> contains NamedUnknown not
68 -- in <vars> or NumericError if result cannot be computed.
70 raises NotEvaluable,NumericError;
73 ---Purpose: returns a string representing <me> in a readable way.
