Glossary
aplet A small application, limited to one 
topic. The built-in aplet types are 
Function, Parametric, Polar, 
Sequence, Solve, Statistics, 
Inference, Finance, Trig Explorer, 
Quad Explorer, Linear Solver and 
Triangle Solve. 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.
