It will be awesome to have limit solver in ti84 :)

I see no particular reason why that couldn't be done, even in BASIC.
But the lim(x-> oo) stuff, it cant be done, right?

I never actually realized how slow the SciTools app was until this year, when I'm actually using it heavily. I also didn't notice that it redraws the whole screen for every single menu movement. That's just sad.

It can.

The ti89 solves limits correctly, so it is possible.  A side note, I already am working on a cas (gCAS2) for GlassOS, which runs oncalc and on PC.  I haven't worked on it recently, but it can parse, create a node tree, simplify and approximate it, and create output, including steps in simplifying the problem... :-D

SDCC tastes like air bags - big output, but fast and safe to run.

If I am able to do this, it would be something very simple. Perhaps more of a "symbolic manipulator" thing. Mostly I want to do this just for fun, and to learn more about the subject. I am currently researching all I can about CAS systems in general. If anyone can recommend materials for that, let me know.

I remember critor made a tool called Autocalc that, if combined with prettyprint, MathPrint OSes and Symbolic, acted like a CAS kinda.
Also, Symbolic is released with the source code here.

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 have always been interested in the theory behind Computer Algebra Systems, but most of it is way above my own current knowledge!  I wish you luck! :)
