TI-84 program for indefinite integrals?
« on: March 01, 2014, 09:51:21 am »
hey guys,

the symbolic app has a feature to calculate derivatives (the d( function)
could a function like this also be programmed for indefinite integrals?

i've been searching for a function like this for almost a week now and it's driving me crazy  :mad:
any help would be appreciated  :thumbsup:

No, unfortunately this is almost impossible except for basic integrals of polynomials like x^2. Mathematica solves indefinite integrals using the Risch algorithm, which is quite difficult to implement.

ZoomMath 500. Be prepared to shed out 100 dollars though.

I bet they have only sold a few copies.

There isn't a free one out there as far as I know, feel free to make one :)

It depends. Since it's math-related and maths are 99% of TI calc userbase, it might be selling more than we think, although there's the issue about overly paranoid parents when it comes to online transaction security, and most students are under 18 so no credit card nor Paypal account. Also wasn't there a version of ZoomMath that costed $500?

ugh, i'm not buying zoommath, i just hate the fact that they charge money for it :mad:
i'd rather spend my summer vacation trying to program one myself (even if it's impossible)

Well, at any rate if Zoommath does it, it shows itself to be at least partially possible.

Spoiler For IMPORTANT NEWS!:
Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

i was wondering, does anyone here actually own zoommath?
is it illegal to (partially) share the code?

ZoomMath is free to download so you could look through the code yourself. What you buy is a key to unlock all of the features.

ZoomMath would not be at all impossible to rewrite. Take Symbolic and work from there to make a full-fledged CAS. In the end it would probably have more features.

really?
does anyone know how i could decompile an app and look through the code?

The main concern would be speed. You can't afford to spend 5 minutes waiting on a result from your calculator.
Decompiling an app is simple. The are online disassemblers, you can find em under 'tools' on the frontpage. You'll have to figure out which code does what,  though, because comments aren't compiled ;)

so, it's been a while now, and i've decided that i still want to calculate my indefinite integrals
so how do i decompile zoommath?

For the most part, decompiling an app and determining the structure of and purposes and functions of the code is simple. In fact, I used to do this without actually decompiling (although it was slower) and just reading bytecode.
According to aeTIos, there is a tool at Omni for it...
Keep trying.
