Digital Cameras Photo Reviews of Texas Instruments(R) TI-89 Graphing CalculatorCustomer Review: Simple, powerfull Summary: 4 Stars
The only thing that I've never liked is that the letters in the screen are way too little, it takes time to get used to it(specially if you are a ti86 or hp's calcs former user), when compared to the newer hp models (50g and so on..) its a toy because of the lack of speed and memory(even the titanium model, try to solve a 21 degree polinomial ecuation in it... and yes some people has to deal with those monsters in real life situations) but its easier to get aroud with it.
Pros:
Easy to use.
Updatable.
Lots of free apps.
cons:
It doesnt work well with hyperbolic functions(EE needs those).
too slow.
Description of Texas Instruments(R) TI-89 Graphing CalculatorEssential for 16-18, university and beyond, the TI-89 is the most logical graphing calculator for advanced mathematics studies. Enhanced with Flash technology, this graphing calculator gives you the flexibility to add calculator software applications and additional functionality, providing long-term value. The TI-89 is allowed for use on the AP Calculus, AP Statistics, AP Physics, AP Chemistry, PSAT/NMSQT, SAT I, SAT II Math IC & IIC. Real and complex numeric results Symbolic manipulation for algebra, calculus and differential equations Numeric evaluation of functions in tables and data variable format Interactive analysis of function values, roots, maximums, minimums, integrals, derivatives, intersections, inflection points, and arc lengths Recursively-defined sequences access any number of previous terms Slope and direction fields for exploring differential equations List-based one- and two-variable statistical analysis, including eight regression models Statistics plots including scatter, xy-line, box and modified box plots Histograms and regression lines Matrix operations including inverse, determinant, transpose, augment, elementary row operations, and reduced row echelon form Matrix elements can be real or complex and numeric or symbolic Column-logic expressions in data/matrix editor are retained for automatic recalculation when values change Hexadecimal and binary operations and conversions Differential Equations: Exact symbolic solutions of many 1st- and 2nd-order ordinary differential equations Solve single or systems of differential equations using Euler or Runga Kutta methods Graph slope fields or direction fields Linear Algebra: Eigenvalues Eigenvectors Functions of matrices (like e A) LU or QR decompositions 3-D Rotation and Contour Plots: Real-time rotation of 3-D surfaces and contour graphs Units of Measure: Use units in equations, symbolic computations, and unit conversions Select from 20 constants and over 100 units Create and sto
