One of my pet peeves about my nSpire CAS, is that: although it is marketed as a CAS, it sometimes doesn't work the way I expect from a $150 device. One of these things that fail is "FOIL"-ing, also known as First Outer Inner Last. When working with many math equations such as factoring or quadratic stuff, many (2x-4)(4x+2)-like (in format) strings come up and become very tedious to solve or simplify. That's why I figured out AutoFoil! It saves time with the whole FOIL thing and saves paper space! (And it helps me be lazy. )

This program is also very easy to work with. In fact, with the recent 3.0 update, a wizard for AutoFoil has been implemented. But to keep nice with 2.0 users, I have also included a "legacy" version inside the program file. The program is very straight-forward. Give the required inputs and you're done. For the legacy version however, you must include in this format: (f1,f2,f3,f4).

Commands: (Must be accessed from the library function, be sure to refresh libraries)
*autofoil: Launches the autofoil wizard
*autofoillegacy: (f1,f2,f3,f4) Takes the inputs and simplifies it using the FOIL method.
*about: credits and such.

How to install:
1. Open up nSpire Mac/PC software.
2. Load Autofoil.tnc to your calculator
3. Disconnect calculator
4. Refresh libraries. (Doc>Refresh Libraries)

DOWNLOAD HERE: (Removed. See the TICalc.org page.)

I should mention that symbolic things only work on CAS. To [attempt] to use on the regular nSpire, rename the tns extension to tnc.

Enjoy!~

My brother has a nspire(non cas) which I don't even go on, but I hope this will help other people who do have a CAS and have these dificulties. Good to see you already released a program. Good luck with further programming.

Thanks.

To the community: Would you much perfer if I had a "output" var recorded after the program is complete or would rather use the arrow keys to select the output? The "done" line is very inconvenient for normal use.

I like output variables personally. This looks nice. I have a nonCAs that doubles as a CAs currently so I can use it symbollically and regularly

Welcome to omni. Have you posted an introduction topic yet so you can get your peanuts? I wish you great luckin programming further on the nSpire

Alright, I'll add that.

You dual-booted your device? Or did you hack CAS software into it?

Yea, I got my peanuts. And thanks for the warm welcome.

Oooh. I'll look into that.

I have to submit a form to get my app listed in the directory, right? A forum post won't do?

Hm. There doesn't seem to be a "[nSpire Apps] Math/Science" app section.
 I'll try to get in touch with an admin.

Oooh. I'll look into that.

I have to submit a form to get my app listed in the directory, right? A forum post won't do?

Either a forum post or a ticalc.org submission would do.

This looks like a nice and useful math tool, by the way. Unfortunately however, you would not be able to upload it in the file archives section, because Omnimaga only accept files related to game development or games themselves, since calc gaming and game programming is our primary focus and we unfortunately did not plan to change that in the future (although people are still welcome to announce non-game programs on the forums).   (After all, we almost changed our site slogan to "Omnimaga: Because Calculators Aren't Just For Maths" until I discovered Deep Thought already used it on his site )

Just open the file then, and enter the commands for it I don't autofoil is a lib doc. But if it is, to access it anywhere, type:
<name of document>\<command>()
autofoil\autofoil()
^Is an example

Oh, don't type those keys. I was saying that that's where the commands and the document name go.
So if the doc was named auto and the command was foil, it would be:

auto\foil()

Make sure it's in MyLib
