17 class ArgCosh from Expr
19 inherits UnaryExpression from Expr
21 uses GeneralExpression from Expr,
22 AsciiString from TCollection,
23 Array1OfNamedUnknown from Expr,
24 Array1OfReal from TColStd,
25 NamedUnknown from Expr
27 raises NumericError from Standard,
28 NotEvaluable from Expr
32 Create(exp : GeneralExpression)
33 ---Purpose: Creates the ArgCosh of <exp>
37 ---Purpose: Returns a GeneralExpression after a simplification
38 -- of the arguments of <me>.
39 returns any GeneralExpression
43 ---Purpose: Returns a copy of <me> having the same unknowns and functions.
46 IsIdentical(me; Other : GeneralExpression)
47 ---Purpose: Tests if <me> and <Other> define the same expression.
48 -- This method does not include any simplification before
55 Derivative(me; X : NamedUnknown)
56 ---Purpose: Returns the derivative on <X> unknown of <me>.
57 returns any GeneralExpression;
59 Evaluate(me; vars : Array1OfNamedUnknown; vals : Array1OfReal)
60 ---Purpose: Returns the value of <me> (as a Real) by
61 -- replacement of <vars> by <vals>.
62 -- Raises NotEvaluable if <me> contains NamedUnknown not
63 -- in <vars> or NumericError if result cannot be computed.
65 raises NotEvaluable,NumericError;
68 ---Purpose: returns a string representing <me> in a readable way.
