it would e kool if someone could make two programs like one could be to input a quadrolic eqation and having it solved like when Y=some # or one that could simplify radical form that would be kool if ur woundering im in corplus 2

I need a program that ranks data for my statistics class. Right now I use the lists in the calculator and this takes me five to ten minutes to solve a problem. I have a TI-83 Plus.

im not sure what you mean by ranks, but under stat there is a sort by ascending or descending order function. sortA([list]) if you want to quickly fill a list with consucutive numbers (ie. 1,3,5,7 or -2,-2.3,-2.6) the visit my website and look at "LISTFILL" feel free to email me

Hi I want a program that will tell me after I were to put in a number for all the denominations of moneym the amount of each no of each denomination if I gave it a figure to take out

I want to know a reverse formula. It is best to show what I mean by example. eg.
I ask the calculator for number of $100 notes, $50 notes $20 notes ...... .05 cent coins in a till at the end of day. From this the calculator adds the total cash in the till and then takes away $300 and gives you a figure. I got up to this step in the program. This figure needs to be taken out of the till in the greatest possible denominations for the banking. For the figure I want the calculator to tell me how many of each denomination to take out. The total of all the denominations of cash must equal this figure. This is so the $300 left can be left for the next day of service and still have all the coinage and notes of least denomination for change tommorrow. I know it is very complicated and complex to understand, but I want find out how it is worked or if anyone and already made a program for it. Thank you for your time. Sarah

well i made a program to solve equations but it can only use one varibale, be a whole number or somthing .5 and it takes a while and has to be between -250 and 250

I have tried to make a program to for the quadric formula but it gives the wrong answers.

You need (2A), not just 2A.

I made a program to solver equations like 1/(x+2)=33

but the problem is it is slow and when X=-2 an error will occur

I despratly need someone to convert a basic program to assembly for me (the program tak

I desperately need someone to convert a basic program to assembly for me (the program takes up only 435 bytes of memory). If you are willing to do this for mw, e-mail me at chiph588@aol.com.

I've been looking for a program that approximates the functionality of dedicated project calculators. I use one daily on our engineering projects to perform conversions from feet/inches to decimals or vice-versa. Now, before the flames come in, I know that these functions can be accessed through the built-in unit conversions, but these can hardly be considered 'handy'. If anyone has used one of the popular project calculators, you'll understand how nicely they do their job and how easily (I belive) it would be to set up the F-buttons to approximate that functionality. Thanks!

hi
I need help for act help like midpoint and distance and quadratic. and all other program.

Can anyone show me a program to do System of equations with three varibles?

Hi everyone!
I got a few problems inventing a program to a family tree analysis...

Maybe you know what to next...

The task was:

One couple of rabbits is born. After two months, it begins to born another couple. This new couple of the second generation has the same information initials, so just after another two months it starts out to spread a new couple, while all other couples are able to born anew couple of rabbits for each months after the first "two- months-step". ^^

Then I got the numbers for 20 generations (=n).
The beginning starts out with 1,1,2,3,5,...
to get the following value of each number, you simply have to add the number of the generation that came before the "n-ed" generation... example: 3(4th gen.)+2(3rd gen.)=5(5th gen.

Thats the fibonochi sequence

I love the Fibonacci Sequence

0, 1, 1, 2, 3, 5, 8,, 13, 21, 33, 54, 87, 114 and so on.

I've worked on creating a program that solves a solution for every variable for whatever variable is missing such as AB^X just to throw something out. How can I make a program to graph the answer after it finds the answer?
celmereian@hotmail.com would be an applicable adress to send if you want to do that.

I was wondering if anyone had a program or could write one for the TI-83 series that could calculate derivitives using the power rule, product rule,quotien rule,chain rule, and general power rule. Thank You

I'm new to the calc. programming world, as is why I'm here. I made a very basic program, but I have a problem... When the answer the calc gives is too big to fit on screen, it won't let me scroll to see the full answer... Any ideas on correcting this? Also... I want the program to loop, which I did fine, but I don't know how to set a key to break the loop... Or something along those lines... I just hit on and then enter to continue and home to get back... Any help would be much appreciated.

Prgm
Loop
Prompt a
Disp d(a,x) //derivative of a with respect to x
EndLoop
EndPrgm

As I said very basic but it helps me out a lot in the tediousness of calculus homework.

As a side note my 2nd attempt at a program turned out nicely... all it does is display the 6 trig. derivatives when I type in the prog. variable, but it sure helps a lot in memorizing them. :) thanks all

Hi, I am new to this board..And ive been hunting all week for a program for Exponential Growth and Decay also, identifying a function as linear, quadratic, or exponential...If someone could give me this I'd greatly appreciate it. im a stuggling in Algebra 2 right now
