I've been pretty new to this calculator programming, and a bit of experience for programming computers (HTML and BASIC type things).

Well, anyway, I've come up with a new concept which is the Formulator, originating from a formula program for my own personal use. The concept is mainly to create a *Customizable* formula program revolving around making only the formulas you need available. In other words, with Formulator, you can save valuable space if there are formulas you just dont need.

The main program has already been created, and right now it supports basic geometric formulas. However, I'm updating the program to support new formula packs (the groups of formulas you get together that are related), including conversions, physics, advanced geometry/trignometry, mechanical, electrical, etc. The soon-to-be Formulator V1.2 is planned to handle a wide number of formula packs, and after that I can create each formula pack individually without need for modifying the main software. The formula packs themselves take little time to create.

This whole idea revolves around an index system I made up, using a single variable to index the software on what formulas you have installed (after setting the variable with a configuration).

I will need support for testing mainly. I already have enough resources at my disposal for finding formulas.

Hey ive been programming on a TI-83+SE for a year and i've made a math program that even shows work! (sorry, i haven't sent to the archives) Anyways... the algorithm to make it show work is pretty slow. Although its written in BASIC i know a simple way to speed it up. I have a program that converts numbers to strings. Is there a way to convert numbers to strings (the user variables X and str1) in ASM?
(I already know some ASM)
Any help would be greatly appreciated. Thanks

A new fourier wave generator program is being created. The program will be released very soon, as there are a few equation bugs to work out.

The current version supports up to five different waveform frequencies (one base frequency and four harmonics). An update will contain an additional five harmonics to enable waveform resolutions of ten frequencies.

If there is someone who can port this graphing program into an audio-generating program (as Fourier analysis involves separating the frequencies of noise), then please contact me.

The Fourier Synthesizer V1 is completed and now has a maximum individual wave capacity of ten. The program will appear on the website shortly.

The next update to this project will be:

A) Expanding the maximum combined waveforms to 15.

B) Separating the Amplitude and Frequency variables so that you can make more interesting and accurate waveforms. F1,F2,....F15 will now be multiplyers of the same base frequency F. F will also have a settable value to allow you to move the waveform up and down the Y axis.

Hey, I recently wrote a program using the built in programmer on the TI83+ It's called "Equations" and has the Law of Sines and Cosines. It has a quadratic formula solver, and the most remarkable feature is it's geometry section. It can do triangles, rectangles, and literally any regular polygon up to about 9999999999999999 sides, or something like that. It has the same stuff for pyramids and prisms along with cylinders, cones, spheres, and of course, circles. And my newest addition is a 3 way compound interest calculator allowing you to find the time it would take, the amount you would have, and the amount of regular input needed to get to a certain amount. And the whole thing is extremely user friendly. And it only takes up about 3000 bytes.

I was wondering if anybody thinks i should add anything, and if it sounds good enough to add to the archives. Please respond

GOOD ENOUGH TO POST TO THE ARCHIVES???? THAT SEEMS LIKE ONE OF THE MOST ARCHIVE-QUALIFIED MATH PROGRAMS I'VE HEARD OF-just make sure the name starts with something like 0-otherwise no one's going to be able to find it in the thousands of '83+ BASIC math programs.

Thanks for the compliment.
Actually, I put it up long, long, long ago. I made about 100 new changes and fixes, then posted it, then made more fixes, sent it in, and recently I added a whole lot of stuff which really went over well with everyone in my school. It's beautiful. The program is called AQUATIONS, but right now it hasn't been updated, so keep an eye out for the Final update. TICALC has been falling a bit behind. Thanks again. E-mail me at Usentian@worldnet.att.net for any questions or comments.

im making a basic program that solves the quadratic formula (i know there are a lot), but mine is going to also solve quartic (Ax^4...) and cubic (Ax^3...). it only has one bug that i know of, but its BIG. its in the cubic solver, but it can throw an answer off by a lot. i need help with fine tuning it and adding some features on it. if you know how to put in simplified radicals, fractions, etc. it will be greatly appreciated. thanks in advance

i've got it almost perfect! only problems are that it gives a domain error for Text(20,8,"x=",-B," +/- sqrt(",P. it also gives some other error for ...,P) and ...,P,") and ...,P,")" i can get it to work anywhere but on this program. cubic problem is still there...

i fixed the quadratic problems, but the cubic is hopefully fixed within the next week!

I'm soon going to have a port to the 83/83+ of my popular 86 BASIC program, FactrP, done. It factors a second, third, or fourth-order polynomial.

Anyone even the smallest bit interested?

i am, but i dont know about anyone else. could you please send me a copy?

bhbwboeckel@hotmail.com

I'm pretty sure I sent it.....did you get it? Is it useful? (Sorry-having people like want my programs is a new experience :) ).

i didnt...bhbwboeckel@hotmail.com (in case i spelled it wrong)

OK, I sent it again.

I am interested!! could you send me a copy? The e-mail above should do it...thanx

Sent.

Almost have a trinomial version working....

OK, it's working and uploaded.

Now has *282 downloads*!!!
