30 Appendix A – Glossary

app

A small application, designed for the study of one or more related topics or to solve problems of a particular

type. The built-in apps are Function, Advanced Graphing, Geometry, Spreadsheet, Statistics 1Var, Statistics

2Var, Inference, DataStreamer, Solve, Linear Solver, Triangle Solver, Finance, Parametric, Polar, Sequence,

Linear Explorer, Quadratic Explorer, and Trig Explorer. An app can be

lled with the data and solutions for a

specic problem. It is reusable (like a program, but easier to use) and it records all your settings and

denitions.

button

An option or menu shown at the bottom of the screen and activated by touch. Compare with key.

CAS

Computer Algebra System. Use the CAS to perform exact or symbolic calculations. Compare to calculations

done in Home view, which often yield numerical approximations. You can share results and variables between

the CAS and Home view (and vice versa).

catalog

A collection of items, such as matrices, lists, programs and the like. New items you create are saved to a

catalog, and you choose a specic item from a catalog to work on it. A special catalog that lists the apps is

called the Application Library.

command

An operation for use in programs. Commands can store results in variables, but do not display results.

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.

Home view

The basic starting point of the calculator. Most calculations can be done in Home view. However, such

calculations only return numeric approximations. For exact results, you can use the CAS. You can share results

and variables between the CAS and Home view (and vice versa).

input form

A screen where you can set values or choose options. Another name for a dialog box.

key

A key on the keypad (as opposed to a button, which appears on the screen and needs to be tapped to be

activated).

Library

A collection of items, more specically, the apps. See also catalog.
