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
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.
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 specific
item from a catalog to work on it. A
special catalog that lists the apps is
called the Application Library.
