TI-89 Features On a TI-83 Plus

[Newbie]

Pretty much what I'm asking is if the below features for the 89 exist for the 83 Plus

The major advantage of the TI-89 over lower-model TI calculators is its built-in computer algebra system, or CAS. The calculator can evaluate and simplify algebraic expressions symbolically. For example, entering (x^3-x^2-8x+12)/(x+3) returns x2 − 4x + 4. The answer is pretty printed by default; that is, it is displayed as it would be written on paper, as opposed to x^2-4x+4 returned by calculators which are incapable of displaying superscripts or subscripts. The TI-89's abilities include:

* Algebraic factoring of expressions, including partial fraction decomposition.
* Algebraic simplification; for example, the CAS can combine multiple terms into one fraction by finding a common denominator.
* Evaluation of trigonometric expressions to exact values. For example, sin(60°) returns \frac{\sqrt{3}}{2} instead of 0.86602.
* Solving equations for a certain variable. The CAS can solve for one variable in terms of others; it can also solve systems of equations. For equations such as quadratics where there are multiple solutions, it returns all of them. Equations with infinitely many solutions are solved by introducing arbitrary constants: solve(tan(x+2)=0,x) returns x=@n1π-2, with the @n1 representing any integer.
* Finding limits of functions, including infinite limits and limits from one direction.
* Symbolic differentiation and integration. Derivatives and definite integrals are evaluated exactly when possible, and approximately otherwise.

In addition to the standard two-dimensional function plots, it can also produce graphs of parametric equations, polar equations, sequence plots, differential equation fields, and three-dimensional (two variable) functions.

Symbolic is about as close as you get http://www.ticalc.org/archives/files/fileinfo/228/22851.html

More complex symbolic math functions are certainly possible, though they would probably be rather slow, consume a lot of memory, or both.

I'd guess the main obstacle is no one wanting to code the algorithms in assembly. Symbolic integration, to take the obvious example, is a lot hairier than symbolic differentiation, and as a result, would be considerably more difficult to write and debug. (Anyone who's taken first-year calculus ought to be able to write out the complete algorithm for Symbolic's d( function, even if they wouldn't necessarily know how to translate it into assembly.)

Search ZoomAlgebra. Get the demo and experiment in your calculator ~~

Download PrettyPrint, Poly Root Finder and simultaneous equation solver (from TI, bah something half well done).
See some of this basic programs: http://www.unitedti.org/index.php?showtopic=8444 (happen to be mine and recently discovered/rethinked some optimizations for size) I think I will use necromancy in that post.

And wait for: http://www.ticalc.org/archives/news/articl...144/144039.html

If anyone knows more than this, I would be very glad to see.

I've recently found something similar, but its in french:

Its half assembly, half BASIC so it is a bit slow, but it works great!
