Catalog,
Level 2/Argument 1: An algebraic expression in tenns of
the cun'ent variable.
Level 1/Argument 2: A list of values for which the
expression is to be evaluated.
Level 2/Item 1: The algebraic expression.
Level Idtem 2: A list containing two lists: a list of the
values and a list of the corresponding results.
Exact mode must be set (flag -105 clear).
Numeric mode must not be set (flag -03 clear).

Command
For a rational fimction of the cini'ent variable, computes
the variation table, that is the turning points of the
function and where the fimction is increasing or
decreasing.
Catalog,
(CAT)
A rational fimction of the current variable.
Level 3/Item 1: The original rational function.
Level 2/Item 2: A list of two lists. The first list indicates
the variation of the function (where it is increasing or
decreasing) in terms of the independent variable. The
second list indicates the variation in tenns of the
dependent variable.
Level 1/Item 3: A graphic object that shows how the
variation table was computed.
