Advanced
Mathematics Software
Includes a Computer Algebra System (CAS), differential
equations, 2D-graphing and data analysis, 3D-graphing with
rotations, linear algebra, interactive numeric solver,
constants, unit conversions, statistical regressions, and
optional assembly language programming.
Pretty Print
Mathematical expressions appear on the display the same way
as they are written on the board or in textbooks.
Over 500K of Memory
Contains about 188K user-available memory and 384K of user
data archive for storing functions, programs, and data.
Electronic
Upgradability
Extend the life of your TI-89 by electronically upgrading
software as new functionality becomes available. TI-GRAPH
LINK™ accessory needed to upgrade software.
High
Resolution Display
100 x 160 pixels on a high-contrast display allows easy
viewing of information. A new screen technology and layout
make the display easy to read.
Symbolic Manipulation
The CAS built into the TI-89 allows you to evaluate
mathematical expressions symbolically or numerically.
Symbolic Differential Equation Solving
Compute exact symbolic solutions to many 1st- and 2nd-order
ordinary differential equations.
Linear Algebra
Find eigenvalues, eigenvectors, functions of matrices (like
e A ), and LU or QR decompositions.
Split
Screen Mode
Split screens allows you to view 2 applications at the same
time.
3-D Rotation and Contour Plots
Real-time rotation of 3D surfaces and contour graphs help
you visualize in 3D.
Units
of Measure
Use units in equations, symbolic computations, and unit
conversions. Select from 20 constants and over 100 units.
Create and store your own custom units.
Numeric Differential Equation Graphing
Solve single or systems of differential equations using
Euler or Runga Kutta methods. Graph slope fields or
direction fields.
Systems of Equations
Solve systems of linear and nonlinear equations. Display
results in general or matrix formats.
Programming
Programming options include custom menus, dialog boxes, and
pop-up windows. User-defined functions extend built-in
functionality.
Catalog of built-in functions
The catalog provides syntax listings for every command and
function.
Compatibility
The TI-89 Advanced Mathematics Software is identical to the
TI-92 Plus Advanced Mathematics Software without the
Geometry application. The TI-89 ViewScreen calculators work
with the TI-92 ViewScreen panels. Data and programs will
transfer directly to and from a TI-92 Plus using the
included unit-to-unit link cable.
Input/Output Port
Allows linking with TI-89s, TI-92s, CBLs, CBRs, and
computers.
