Today it is with great honor and pleasure that we are finally announcing the release of FormulaPro !
What is FormulaPro ? Here are the technical details : FormulaPro is a TI-Nspire (OS 3.x) document whose main content is a Lua script. Yep, all made in Nspire-Lua (http://www.inspired-lua.org). Indeed, it is the only way so far / right now to "properly" achieve what we do on FormulaPro (completely graphical UI, math calculations...). FormulaPro is also free, of course, and open-source (https://github.com/adriweb/EEPro-for-Nspire/) (LGPL license) !
Hmm ok, but what does it do ? Well, here you go : some of you may already know what's called "EEPro" or "MEPro" for the TI-89 and TI-92. It is an official program that TI puts in the 89 by default. If you don't know it, EEPro-89 is basically a program described by TI like this: "This application solves the problems of electrical engineering. It is composed of three modules: Analysis, Equations (700 equations grouped into 16 subjects) and Reference. " In short, a complete and very powerful application about Electrical Engineering. Well, FormulaPro is the 2nd part ("Equations") of our project to port the EEPro-89 suite to the Nspire. But we improved it, naturally. A lot. (And we already have plans and written code already ready for version 2.0 which will be even more awesome and more powerful.)
What FormulaPro right now is capable of, along with its website, is : to be able to run on any OS 3.x and any Nspire model and to be able to run on the computer software too with auto-resizing frames Mouse and keyboard input support, on both Software and Handheld to be able to let users generate their own pack of equations, smartly (variables and units are bound), within categories and sub-categories, to be able to solve intelligently solve the equations it's given, contrary to the 89 version, where the user had to select what equations had to be used : Indeed, here you just have to enter what you know already, and it will automatically try to solve for what it can. it can very easily let you chose the unit/subunit you want to enter your data in. (for example Hz/kHz/MHz, °C/°F/°K etc.) it can show you the used formulas of the current sub-category in "PrettyPrint"
Great ! How do I use it ? Be sure to run Nspire OS >= 3.0. We recommand version 220.127.116.112. You can then either use the "demo" database (a part of the original EE-Pro one) available here (and also attached) : https://github.com/adriweb/EEPro-for-Ns ... s?raw=true … or either starting your own database with our online FormulaPro Database maker which lets you easily create categories, subcategories, equations, units and subunits etc. It is available here: http://education.bwns.be/FormulaPro/ If you were on the online generator, click the "Generate" button at the bottom of the page. Transfer the .tns to your calculator or in the computer software and open it. Select the category and the subcategory, and begin filling the input fields of the data you already know. Press enter or change focus, and it will start auto-solving. Enjoy !
Screenshots time ! Here are 4 screenshots showing pretty much all of FormulaPro. They are not related to each other. , , ,
What's next ? Well, we will try to complete the entire Formula library from the original EEPro-suite. (This is just a matter of time, so it's no problem, really) In general, the plan is to be able to do everything (and more !) that the TI-89 version can do.
So, here's what we also planned for version 2.0 : Database Editing on-calc ! An even more powerful solving core Smart Search (Don't browse in the categories : just enter the units you have and it will try to figure out which equatinos to use directly) Pictures associated with categories (circuits explanations etc.) Input data directly into the solver using Vernier sensors! Multi-language support Ability to graph results …
Thank you! I have been waiting for this program however, it does not work correctly on my handheld. The document opens and works fine for the student software, but when I open the file on my handheld and try to click one of the choices my handheld locks up and freezes. I am not sure if it has anything to do with my OS which is the new 3.2. Any suggestions?
For now, just press Enter to navigate. We'll fix that as soon as possible. (i've also noticed that if you make the mouse appear after it "freezes" and click with the touchpad on a scrollbar button (bottom), it will work ...)
Also, we released a versino with a solved freeze issue (on certain cases for solving equations)
Thank you for the link. It did not fix my issue entirely, but it's no problem as I can live with it since I am able to use the enter button and it is a much needed program for my studies. Again, I appreciate all the efforts you guys have put into the program.

No problem, we will soon update even more with more and more formulas, I'll let you know
By the way : to get out of the freeze, just press [tab], for example. (there is a focus issue we are woking on to fix)
