TabVar v3 , the ultimate function analysis program !
« on: October 29, 2011, 05:45:38 pm »
Hi everybody,

Today is a great day!

Indeed, for the lucky owners of a TI-Nspire with OS >= 3, JayTe has made an awesome program that combines the simplicity of the TI-Basic with the power of Lua, for our pleasure ...
Here is ... TabVar 3 !
Yes, the famous program that makes all your work in depth and draws a beautiful variations table ("Tableau de variations" in french) !

"Hmm, Doesn't that exist already ?" You might say.
It does, actually, The idea is not new.
Chronologically, it has indeed been made by Adriweb, the first one for Nspire, and then, TabVar v1 and v2, by JayTe, whose engine is based originally on Adriweb's program, but everything was done much further by integrating more and better function analysis functions and algorithms.

This program exceeds by far its competitors. No other .tns can hope to compete so far.

The outstanding feature of this version is that this program (launched exclusively on TI-Planet) deeply uses the features offered by the OS 3 by integrating a dynamic Lua script for an optimal view of the variation table, which for once is completely graphical. No need to have weird graphical hacks to correctly display what we need ...

We will not make you wait any longer... Here's a screenshot of TabVar:

and details of preliminary calculations (click for larger image):


So far, you will not find a more reliable engine (although nothing is perfect, of course, complex functions can be studied incompletely ...)
You can, for example, try fairly complex functions, such as polynomial, rational, with or without asymptote(s) and strange behavior with or without limits ...
In short, for a high school student (or other!) It's more than perfect :-)

Thank you Who?
Thank you Jayte!

Do not forget, this program is by far the most reliable and practical for the studies of functions ..
A small screenshot to prove that point ?
(Example : TabVar v3 against a competitor for the same function f(x)=1/x)

Yep, do not trust bad imitations if you want a good grade!

Great ! I am now able to cheat check my results :P

...by Adriweb...
But, aren't you Adriweb ? The "by Adriweb" makes us think you like yourself a lot :P
I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

I also mentioned it on ti planet.
the programn needs CAS, quite essential to leave it out in the description :P
but I think it's really nice for people who have a CAS
KJ
in need of omnoms ? check this out :P

He wasn't the only contributor for this post :D
We prepared it together before posting it.
I do not get mad at people, I just want them to learn the way I learnt.

I've got something similar for non-CAS but it's in alpha stage.

Nice work adriweb. :) I wonder how hard it would be to adapt it for regular CX calcs?
