Post your ideas for new math programs here, or build on ideas posted by other visitors.

Here's a pretty cool program. What you do is select 3 points on a coordinate plane. going from one point select randomly one other point and plot the midpoint. From the that new point select randomly one of the 3 ORIGINAL points and plot the midpoint. Repeat this a couple hundred times and see what you get. I am not going to put up the coding unless someone asks for it. I used 83 BASIC. Check out the result its pretty cool.

would anybody know a good program for like area of shapes that i can make to put on a ti-83 plus??? i just need somebody to teach me how to program and enter the data...

Well, all you would have to do is determine whats the max number of sides you would need and determine how many triangles you can get from diagonals in that figure. There is a equation for this somewhere. It would take some time to create though. Email me and I could start working on this. . . .

Hey guys,
I was wondering if anyone has been able to make a programs that could:
a. solve nonlinear equations
b. solve radical equations (maybe even with 2 radical terms or with index's other than 2)
c. solve with fractional exponents

or even better:
a) solve nonlinear systems of equations
b) solve quadratic and rational inequalities

I've searched pretty heavily but have had no luck! Please help!!
Thanks,

I had a speaker in my math class who talked about cryptology and its mathematical background. She gave us a the following formula to encrypt numbers using prime numbers:

P= prime message #
Q= Another Prime

P*Q = N
E= public "code", relative prime to P so that E<P
Let M = (P-1)*(Q-1)
M*Q+1 = D
C=P^E mod(N), C= message seen

Ex.
P=3, Q=5
N=15
E=2
C=P^E mod(15)=4 mod(15)

Is there is a way to do this to strings on the Ti-89 titanium?

Anyone have any ideas how to write a program on Ti-89 titanium to get critical points and saddle points using partial derivatives?

This is what I have so far:

minmax()
Prgm
Request "Enter f(x,y)",a
expr(a)->a
**First dirivatives**
d(a,x)->q
d(a,y)->r
**Second derivatives**
d(d(a,x),x)->l
d(d(a,x),y)->m
d(d(a,y),y)->n
**Determinant of H**
[l,m;m,n]->h
det(h)
.
.
.

EndPrgm

I need a way of it solving the first dirivatives for y and using one of those answers to replace y in the other and solve for x and give the total critical points.
I then need it to take those points and calculate the det(x,y), fxx(x,y), and f(x,y)

I don't have TI link
I need soure of program Laplace
Please Help me

Hi I was wondering if anyone has tried to write a program that calculates fibbonnachi numbers, I have thought about this and can't figure out how to do it.
This program would have no real practical purpose other than tou give you some really big fibbonnachi #s. I have a ti83+. If someone knows how to do this, could they post it or e-mail me the code in ti basic to jwymbs23@gmail.com.
Thanks.

Hmmm...I need a prime number program, but not the kind that everyone is making...I do math competitions and it would be really useful to get a program where I could find the nTH prime number, or add all of the prime numbers from X to Y...oh, and I don't have a cable, so I would need the actual program stuff sent to me...

I'm making a program dealing with cones and I can't get the total surface area in terms of R (radius). I need R= bla bla bla using Pi, l (slant), and the total surface area. The original equation for those who don't know is: Pi(R)(L)+Pi(R^2)=SA

Is it possible to write a program to simplify rational equations? Its getting really annoying. Thanks.

does anybody have a program that can make numbers like

the sqrt10 =

2 sqrt5

and problems of that sort
e mail or reply on this forum with ideas plz

Omnicalc does that. you'd type in simp[rootsign](20) and it spits out 2[rootsign]5. If you have Omnicalc, you can find simp[rootsign]( by pressing PRGM-PRGM-[Right]-7.

who knows how to program your TI-83 PLUS to say "No Slope" when you get a vertical line, (from finding the slope)???? i need it to work for both vertical and horizontal (with hor. it should just say 0)

i need a program in basic for a TI-83+ that takes in 3 numbers and outputs the greatest number

Simple:
ClrList L1
Prompt A,B,C
A->L1(1)
B->L1(2)
C->L1(3)
SortD(L1)
Disp L1(1)

I am having trouble creating a program that solves a linear equation, and shows the steps used (AKA:Teacher wants her Calculus students to show their work on an algebraic function)

This would save me a bundle of headache...

Im running a TI-84+

Any help? Send it to my email:
uac_felix@yahoo.com (replace _ with a .)( to avoid password sniffers)
Im sorry but I cannot accept attached files...

ok im a student in highschool.. freshmen year.. and my teacher and i have been trying to put ina program that helps solve for polynomials.. the program data he has entered keeps showing up as either argument or non real solution.. if anyone could help find the programming code for polynomials i would really appreciate the assistance
