TI-92 Feature List

All mathematical calculations and operations compute exact, symbolic results, including manipulation of undefined variables.

Expression simplification with standard arithmetical and algebraic operations and parenthetical grouping.
Up to 99 last entries and answers are saved and displayed for quick recall.
Pretty print graphically displays expressions the way they would look on paper, including fractions, roots, and exponents.
Large, 239*103 resolution scrollable display for mathematical expressions.
Graphical user interface similar to Windows and MacOS with menus, dialog boxes, and cursor.
Mathematical functions include numerical operations, probability, angle calculations in radians or degrees, and trigonometry.
Algebraic functions include solving equations, factoring and expanding expressions, converting numbers to fractions, and extracting numerators and denominators.
Calculus functions include symbolic integration and differentiation, finding the length of a curve, finding the minimum and maximum of a function, and finding Taylor polynomials.
Manipulation of complex numbers in rectangular or polar form.
Numbers expressed in floating point, scientific notation, or engineering notation, or to a fixed number of decimal places, or rounded to a specific number of decimal places.
Numbers expressed in exact simplified fractional and radical form and in terms of pi, or in decimal form.
Boolean logic operators with equations, inequalities, and true/false conditions.
Manipulate lists of data

Strings are treated as undefined real variables. ("hello"+"hello" evaluates to 2*"hello")
Greek, international, and punctuaction characters are available.
Calculator uses PC ASCII for most characters.

Graph up to 99 of each type (except 3D functions) simultaneously.
Trace cursor along graph.
Zoom operations.
Control viewpoint with 3D functions.
7 graphing styles
Mathematical analysis and calculus operations of graph. (approximate results, not available in 3D graphs)

Lines, circles, pixels, and text can be drawn on graph.
Save pictures of graph or part of graph and databases of graph (small file which holds graph functions and settings).
239*103 graph resolution
Table (Not available for 3D functions.)

Setup several functions at a time in a table.
Control table starting point and increment value, or set table to match graph window.

Edit multiple lists simultaneously.
Setup calculations between lists. (Example: c1={1,2,3,4} and c2={5,7,8,13}; set formula for c3: c1+c2, to make c3={6,9,11,17})
Sort all lists based on a key list, so corresponding items in lists still match up.

Create points, lines, circles, and polygons.
Perform analytic, transformational, and Euclidean geometric functions.
Geometric objects are relational, so changing the construction affects other objects in the construction.
Take measurements and perform calculations on those measurements.

Type notes or command-line scripts.
Create "lab reports" for printing with TI-Graph Link (unfortunately, no Pretty Print for expressions in printed lab reports).

View two applications simultaneously with the screen split horizontally or vertically.
Set size of window of each application.
View two independent graphs, each having an individual graphing mode, selected functions, window settings, and formatting.

All calculator features except geometry available from programs.
Simple, BASIC-like language.
Standard program control and looping instructions.
Instructions available for user input and displaying data.
Local variables available from programs that delete automatically upon execution completion.
Programs can have command line parameters.
User-defined functions can be created that can be called from any expression or function to be graphed.
