Looking for someone to help program a application for my work itll be beneficial to more then just me. looking for simple interface, e6b flight calculator and some other calculations i need to perform my job easier. email me

I recently got tired of doing the extra steps of finding slopes in Basic Algebra, so here is SLOPEFINDER for the TI-83 Plus:

ClrHome
Output(8,1,"SLOPEFINDER")
Input "X1:", A
Input "Y1:", B
Input "X2:", C
Input "Y2:", D
Output(7,1,"SLOPE IS:")
Output(8,1,(A-C)/(B-D))

Hey, I use the TI-84+ and I am trying to create a program that will let me display more then 9 decimal places without scientific notations... How may I approach this? Fix 10+ results in errors...

Can anyone help me in sharing or creating a program for the TI-84 Plus Silver edition that has to do with adding and subtracting time.
Thanks.

I am looking for a program that solves Catenary problems. I have looked in the archives but was unsuccessful.

I'm thinking of a program that can calculate pi but I just can't get it right. Any thoughts?

I have found a way to shorten the amount of math you have to do in order to solve the Pythagorean Theoreom using this program:

:Prompt A,B
:√(A²+B²)→C
:Disp"HYPOTENUSE IS",C
:

I hope it helps.

I have a request/need help. Maybe this program exists already, but I have searched and could not find one at all! First off, I am on a TI-84. I want a program that can write a quadratic function for a parabola. An equation in vertex form looks like y=a(x-h)^2+k. You would have to plug in the points you see on a parabola. In this case, I 3,2 and the vertex is 1,-2.

Does anyone have a way to do this? So you would just plug in the points via a prompt and it would show the completed equation. Is anyone here capable of such a task? One other thing that goes along with this is a little harder/ You would need to write a quadratic function in standard form for a parabola that passes though 3 points. Has anyone does this or can someone do this?

As a quick background on me, I understand how to code in python, c,and php. I am still getting used to the ti84/basic programming.

If someone can help with this it would be much appreciated. Just reply here or to supermike615@gmail.com

Thanks!

Anyone have an idea for a program that finds orthocenter on a Ti-84+Silver?

I would really like a problem that gives exact radical fractions. Like, if you divide 2sqr5 for 3sqr4, there's it no problem that solves it. I'd like a program that show the exact answer: sqr5/3

I have a TI-nSpire CAS and am looking for a program that will solve linear programming problems. Inputs would be the objective function, constraints (inequalities), whether you want to maximize or minimize the objective function. Then, push a button and whiz-buzz, the answer appears with the x-y coordinates of the vertices in the feasible region of the inequality graphs. Most computer programs use what is called the Simplex Method for solving these optimization problems and I just don't know enough about programming the nSpire or the Simplex Method to do this myself.

DOes anybody know of , or written, a program for the TI-nSpire CAS that can maximize or minimize an objective function given it's constraints

Hi, I am trying to get a group together to create an epic, all-encompassing high school physics app for the TI-83/84 family of calculators. In essence I plan it to be a rich, formula manager that will solve and manage equations for you. If you are interested, I am creating a site to share files and such on- you can contact me through the site listed in the URL field. Thanks!

can anyone help me with how to write a program that could find a nth term in a recursive.

Anyone for a Greene's theorem program??

I am making a 9th. grade STAAR sheet that is totally interactive.

I am trying to make a program that will tell me the equation of a line that passes through two points. I want to do it by finding the slope and then using the point-slope formula. If there is an easier way to do it, tell me! This code is not giving me the right answers.
Here is the code I have:

Input "X1=",A
Input "Y1=",B
Input "X2=",C
Input "Y2=",D
ClrHome
(D-B)/(C-A)->E
E*A->F
F+B->G
Output(4,1,"Y="
Output(4,3,E
Output(4,6,"X-"
Output(4,8,G

Hi there!

Is there a program that 'convert' a formula? (A=B*C => B=A/C)
But with more opportunities for longer formula's. It's just to check if I'm correct. Sometimes I could miss in it by distractibility ... :))

Thx A Lot!! (I hope this forum is still active ... ^^)

Who knows how to make a program for a polynomial function
for example
p(a+1)=5(a+1)-(a+1)^2 + 3(a+1)^3
=...
=...
=...
=3a^3 + 8a^2 + 12a + 7

I'm attempting to write a program involving solving elements of a curve. I'm new to programming and after reading 2 books on the subject I'm still having trouble getting off the ground with it. I'd like to set it up something like
1. Length of Curve
2. Tangent Distance
3. Chord Length
4. External Distance
5. Middle Ordinate
I'm using a TI84 plus C and any help will be greatly appreciated. thanks in advance.

"Eureka the solver" a Borland program from the early 90's. It would be nice if this software could be converted to TI calculators
Especially the solver functionality is brilliant.
The graphing function could be integrated with the already available graphing on the TI calculators.

It is by far the most compact and most complete package of math solver functionality that i have ever seen.

Others have more and look better but consume hundreds of megabytes. This one was created to fit on a diskette (<1.44mb) leaving out graphing and some other already availaible functionality might reduce the size to TI84 compatible size.
