Setting the form
of menu items
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 presented differently depending on what
presentation mode you select:
The default menu presentation mode is to provide the
descriptive names for the CAS functions. If you prefer the
Recursive
Replacement
Specify the maximum number of
embedded variables allowed in a
single evaluation in a program.

tion above.
Recursive
Function
Specify the maximum number of
embedded function calls allowed.
Epsilon Any number smaller than the
value specified for epsilon will be
shown as zero.
Probability Specify the maximum probability
of an answer being wrong for
non-deterministic algorithms. Set
this to zero for deterministic algo-
rithms.
Newton Specify the maximum number of
iterations when using the Newto-
nian method to find the roots of a
quadratic.
