Appendix C: Glossary
This section defines some terms I use in the tips. Some definitions may seem obvious to
English-speaking users, but the calculator community is thoroughly international. The glossary
incorporates (with permission) many entries from Ray Kremer's Graphing Calculator glossary.
@1...@255
Represents an arbitrary constant, where distinct constants are distinguished by the numbers 1, 2 and
so on, appended to the @ symbol. The constant may not be an integer; see @n1 below for
comparison. Arbitrary constants may occur in solutions returned by zeros(). The first arbitrary constant
created is called @1. Subsequent constants are numbered from 2 to 255. The suffix resets to 1 when
you use ClrHome.
@n1...@n255
Represents an arbitrary integer, where distinct integers are distinguished by the numbers 1, 2 and so
on, appended to the @n. Arbitrary integers may occur in the solutions to some equations, for example,
in the expression @n1 + 7, @n1 may be replaced by any integer. The first arbitrary integer which is
created is called @n1. Subsequent integers are numbered from 2 to 255. After the 255th integer is
created, numbering continues with @n0. You may use [F6] Clean Up 2:NewProb to reset arbitrary
integers to @n1.
2D
Acronym for 'two dimensional'. Refers to the calculator graphing mode in which functions one
independent variable are plotted, for example, y=f(x)
3D
Acronym for 'three dimensional'. Refers to the calculator graphing mode in which functions of two
independent variables can be plotted, for example, z = f(x,y).
68K, 68000
Refers to the microprocessor used in the TI-89 / TI-92 Plus, which is a Motorola MC68000.
89
Abbreviation for TI-89
92, 92+, 92p
Abbreviations for TI-92 Plus, although 92 strictly refers to the original TI-92, not the TI-92 Plus.
algebraic entry
Method of typing an expression on the calculator in much the same way that expressions are shown in
text books. Compare to RPN.
AMS
TI's acronym for advanced mathematics software. This refers to the basic operating software
(operating system) for the TI-89 / TI-92 Plus calculators. Various revisions are identified by the version
number, for example, AMS 2.05. Some bugs, fixes and tips only apply to certain AMS versions. TI
seems to be abandoning the term AMS in favor of base code.
Only the most recent version of the AMS is available for download on the TI web site, but TI will e-mail
older versions on request. Your e-mail service must be able to handle the AMS as an attachment,
which is over one megabyte. Assembly programs are often incompatible with newer AMS versions.
