Glossary
aplet A small application, limited to one
topic. The built-in aplet types are
Function, Parametric, Polar, Sequence,
Solve, and Statistics. An aplet can be
filled with the data and solutions for a
specific problem. It is reusable (like a
program, but easier to use) and it records
all your settings and definitions.
command An operation for use in programs.
Commands can store results in
variables, but do not display results.
Arguments are separated by semi-
colons, such as
DISP expression ; line#.
expression A number, variable, or algebraic
expression (numbers plus functions)
that produces a value.
function An operation, possibly with arguments,
that returns a result. It does not store
results in variables. The arguments must
be enclosed in parentheses and
separated with commas (or periods in
Comma mode), such as
CROSS (matrix1,matrix2).
HOME The basic starting point of the
calculator. Go to HOME to do
calculations.
Library For aplet management: to start, save,
reset, send and receive aplets.
list A set of values separated by commas
(periods if the Decimal Mark is Comma)
and enclosed in braces. Lists are
commonly used to enter statistical data
and to evaluate a function with multiple
values. Created and manipulated by the
List editor and catalog.
matrix A two-dimensional array of values
separated by commas (periods if the
Decimal Mark is Comma) and enclosed
in nested brackets. Created and
manipulated by the Matrix catalog and
editor. Vectors are also handled by the
Matrix catalog and editor.
