One setting that affects the CAS is made outside the CAS
Settings screen. This setting determines whether the
commands on the CAS menu are presented descriptively or by
their command name. Here are some examples of identical
functions that are presently differently depending on what
presentation mode you select:
Descriptive name
Factors List
Complex Zeros
Groebner Basis
Factor by Degree
Find Roots
The default menu presentation mode is to provide the
descriptive names for the CAS functions. If you prefer the
functions to be presented by their command name, deselect
the Menu Display option on the second page of the Home
Settings screen (see "Home settings" on page 27).
When your are working in CAS, you can retrieve an expres-
sion or result from Home view by tapping
Get from Home. Home view opens. Press
the item you want to retrieve is highlighted and press
Purpose (Cont.)
Any number smaller than the
value specified for epsilon will be
shown as zero.
Specify the maximum probability
of an answer being wrong for
non-deterministic algorithms. Set
this to zero for deterministic algo-
rithms.
Specify the maximum number of
iterations when using the Newto-
nian method to find the roots of a
quadratic.
