Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

2 Answers

Know a program for the TI 84 Plus SE for factoring polynomials?

I would prefer the source code so I could manually key it into my calculator because I don't trust the websites where you download the programs plus I can never figure them out. I'm kinda coumputer challanged.

    can you please show the source code for something like
    x^2 + 6x + 9 and turn it into (x+3)(x+3)
    if you can...thanks

    To xoshi101 yes I mean the first one, something that could take x^2+6x+9 and turn it into (x+3)(x+3).

  • xoshi101 May 11, 2010

    do you mean something that could take something like x^2 + 6x + 9 and turn it into (x+3)(x+3)?  or do you mean the other way around.  I could probably do the first one.

To know the x'es in something like X²-3X+2=0
use this: Prompt A,B,C B²-4AC->D Disp " " Disp D Disp " " If D>=0 Then Disp (-B-sqrt(D))/(2A) Disp " " Disp (-B+sqrt(D))/(2A) Else Disp "NO SOLUTION" End Pause ClrHome

this gives 1: the location where the graph crosses the x-axis 2: the 2 solutions of X. If none, it only displays the one above and the text: NO SOLUTION

    I have a program that will factor any trinomial into parentheses. It will even pull out the GCF and place it in front of the parentheses.
    The only problem is that i cant get the code cause the program does not let me edit it.
    If you know of a way that I can get the source code, i will gladly send it to you.
    I only know how to transfer this program from calc to calc.
    email me at erathfon2000@yahoo.com if you know how i can get it.

    @erathfon2000 the program was not written in TI-Basic it was written on a computer probably in a version of C and compiled into a format the calculator can understand. it will run but the source can't be viewed on the calculator you could try uploading it to your computer and getting a decompiler and decompiling the program, sorry but I can't suggest a program to use. I am just getting into coding I am currently learning Java

Factoring on the ti-83


Natively it is unable to factor out polynomials. It does not have a CAS (Computer Algebra System). You may have confused it with some other CAS-enabled calculator.

The TI-84 does not have a built-in quintic fit.

The most common scheme for fitting a model to data is the least squares. You'll find several programs to calculate this here.

Window settings TI 84


Unfortunately there is no single "correct" set of window parameters. It depends on the particular polynomial.

Consider this: after you get a good plot of a polynomial, try plotting another polynomial derived by dividing all of the coefficients by a million. If you plot it using the same settings, the graph will be indistinguishable from the X-axis.

Comma key on TI-84 Plus Siver Edition calculator.


The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.

Ti85


kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.
The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

TI-82: $89
TI-83 Plus: $79-99
Free TI-85: $0
TI-84 plus: $119.99
TI-84+SE: $129-139
TI-89 Titanium: $149
