uh....

I'm planning on making a long division of polynomials program. What you do is, you enter the coefficients of the polynomials and then it will divide for you and give you the answer and the remainder. Give me some suggestions on how you think I should display the answers.

It would be great to show it in the form,

x^2 + 3x + 4 + 12/(x-1). Great idea. Let us know how it works out, or if you need any help.

hey i do lots of base problems and i am always needing a remndier i would love to have it if you could e-mail it to me at wild_man_07_@hotmail.com

i suggest showing it in synthetic form too because it gives the user something to write down on their homework.

I'm thinking about numerical convolution program contruction, this is one topic area that poses extream difficulties to programer so far. I strongly believed there are some guru that can handle this so called numerical convolution. I need someone to take on this convolution. I 'm staning by with all my support as well. please come forward if it is you .
thanks

I would have to agree - a program that did Convolution Integrals would be VERY handy for us EE students!

Does anyone have any ideas for a geniune math problem that could be solved with an innovative program? I'm not talking about getting a program to do work in school, but a real program that actually accomplishes something.

I need some help. Like i need to design a program that randomly generates numbers but stops after it repeats one for instance. 1-2-4-5-2, then it would report 4 numbers. which is how many after the first one. i've tried many times, but i can't figure it out, plus i'm not good at programming either. so 1-1, would report 1. 2-5-2, would report 2 and so on. if anyone could help me please email me at weylin@gorillagrape.com, i would really appreciate it.

Ok, this might be a little unoptomized but it would work assuming that you want a integer from 1-5 (its for a 83+). If you want it to go from 1 to another number, just replace the fives with the number you want. I didnt test this, so tell me if it doesnt work:
->=store
ClrHome
5->dim(L1)
For(A,1,5)
randInt(1,5)->B
For(A,1,5)
If B=L1(A)
Then
Disp B
Stop
End
End
Disp B
B->L1(A)
End

It does work, but I updated it. E-mail me at SSpyro64@AOL.com if you want the updated version.

It would be interesting to create a giant program that was essentially a CAS that could perform algebraic manipulation. The 83+ SE has a large memory, so the size of the file could be large. It would have to be a massive organized group venture, but it would be really neat. They'd have to ban all ti-83+ SEs!

Great idea! I'd love to help if a mathematician could be found.

Wait, "they"? The people everyone most cares about is the College Board (makes the SAT), and they allow the CAS-endowed 89, since it doesn't have a QWERTY keyboard, although the other calcs with CAS (the 92(+) and V200) do.

What's a CAS?

CAS stands for "Computer Algebra System." Which means you can input things like: ((x/4)+(4/2x))/((2/3)(x/6)) and it spits out the answer.

bump.
Anyone interested in this still?

i am working on a program that does exactly that. how good are you at programming? because its a lot of work

I have some problems with vectors. My TI-86 can't compile a TI-83 Program. So I try to convert it. My Problem in programing:
:InpSt K
:K->L4(1)
It say's: Invalid Data Typ. Has anybody an idea? If it works it could a very great program :-)

InpSt is not a valid command. Tell me what this command does on the 86, and I can tell you what might be the equivilent on an 83.

For one thing, 'InpSt' is a valid command on the 86. I'm not sure about the 83. I believe that the problem is 'K->L4(1)' The calculator is trying to store the string 'K' to the first term in the list 'L4'. This is possible on the 68K calculators; however, I don't think that you can do this on z80 calcs.

InpSt is not a valid command on the TI-83.
I'm assuming (I dont have an 86) that it means input a string. In this case, you would have to do something like Input "...",Str0 (replace ...with a title)..
K->L4(1) is a valid command

It's inputStr I think; I use a Voyage, mostly, and I never deal with strings.

InpSt takes either a string prompt then a variable to store the response string in or just a variable to prompt for the value of. The problem is that it takes the value that is being returned and storing it as a string. You are then trying to store that string in a place where only a number can be stored. What it boils down to is that you are trying to put a string where only a number can go. You could try parsing the double from the string if its that important to you but i would use different methods. By the way i dont own a TI 86 but with a little research from the online guidebook on Texas Instruments site(in the URL field) it was easy to determine.
