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. |
