I would like a program that could factor with variables. I know ti-86 doesn't support multivariable programs(as far as I know atleast, with the exception of the simultanios equation solver) but even if it could only keep the variables in the same place or just move them around. That would be great. Thanks in advance if its possible.
email me if you need assistance in any way shape or form at rkplumber@nac.net.

Download Omnicalc. It's an app on the site that extends the capabilities of the 83+. There is a factoring function on it. Just input the number you what factored and it will factor it in a list.

I've never been able to use those functions. If you don't mind telling me, feel free to e-mail me at smartguy6519@gmail.com.

If you mean factoring a polynomial, I have a program for that, FactrP, in the TI-86 BASIC math programs.

How would you make a program to solve simultaneuous systems of equations. Also isn't there a way to do that on a matrices?

I could make a program that does it. All that I need to know is what calc you have. Also on a calc just input the coefficients and constants into the matrix and use rref() to get your answer.

If you have a TI86, there's a simultaneous equation solver already there.

And if you have an 83+, then you can download the application that does the Poly and Simult functions on the 86 at the link above or copy and paste without the spaces.....

To solve multiple equations using matrices, just plug in the coefficients. Example: 2x+3y=7 and 4x+5y=9 would be [ 2 3 7 ]
[ 4 5 9 ].
You can expand the matrix depending on how many equations or variable you have. Use it in the function rref() and do the opposite to find the answer.

Nik:To make the program that you want,you must indicate what calc you have.I already have done one program to solve a real or complex linear equations system for the TI-83.It was a suggestion of a friend (circuit analysis...):the calc doesn't treat complex number and the matrices writing is a timewaste...I have done the same program for the TI-85.Just reply or e-mail me what calc you have and I will send the program to you.

I'm working in a basic programs that does the matrix thingy.....and this also:

Functions:Distance
:Slope
:Midpoints
:Extend the line (by findig the next point)
:Inequalities (a little easier that the App)
:Regretion (linear & Quadratic)it gives the resolt as a Y= equation.

A matrix (system) solver and a lot more.....

I was wondering if someone has or could create a program to do long polynomial division? For a TI-83 plus silver edition.

does it look like this?

example:

3x^2+4x-5/2x+9

ax^2+bx+c/dx+e

if that is the case, i have a program for it

Get MathStuf (v.6 comes out on Christmas Day), it has a lot of other stuf with it though...

Can anyone make a program to factor trinomials or polynomials, I'm not to sure how to do it. Plz help.

I've got one. It's posted under TI86 BASIC math programs, and called FactrP. It will factor a binomial, trinomial, or fourth-power polynomial.

is there a program like that for the TI-83+? i could really use it.

If the 86 version is in BASIC, it is highly likely it will work with VERY little editing on the 83+...just use your 83+ manual

I am doing radical expressions i math right now in 8th grade. My friend has a TI-89 and can simplify radical expressions on the homescreen with no programs. The TI-89 can also solve radical expressions with variables. I have a TI-83+ and was wondering if there was such a program for the TI-83+.

Example:
sqrt(24x^6 y^5 z^2)

to this

2x^3 y^2 asb(z) sqrt(6y)

Thanks, Tim Molloy

I have one for simplifing radicals
like
sqrt(27)
3 sqrt(3) //root 27 = 3*root 3

I have a huge math program in basic with close to 100 things on it and was wandering if anyone could provide me with something they wanted included in it before i upload it to their archives. Any ideas would be greatly appreciated.
Thank You
you can email me ideas at jason89@rocketmail.com or just post them here

you probably have this stuff, but here goes: the quadratic formula, volumes, surface area, etc.

Trig identities would be nice.

you can update it later once you update it you know
