Symbolic Math Guide Released
Posted by Eric on 30 March 2001, 22:37 GMT

TI has released a beta of their newest concept app, the Symbolic Math Guide. Well, actually, it's only a "pre-beta" (read: alpha), but the many screenshots look pretty promising, so y'all might want to go give it a whirl. In short, it's a FLASH app that interactively takes students on a tour of various symbolic manipulations.

Thanks to everyone who let me know about this (for the record, Eugene Ho was first).

Again This app shows how slow are the flash apps. Try to naviguate through the help an you will understand ! It takes ages to draw a single text line. This could be achieved faster in TI-BASIC with flib.
Ti should change FLASH-APPS into SLUGGISH-APPS.

That's a crock of bull. Flash Apps are not noticeably slower than a TI-GCC program that uses the same ROM calls. Both compile the C code into ASM which, aside from some usually minor optimizational differences, is for nearly all intents and purposes identical between the two compilers.

Since I've tested the SDK for 9 months now and I'm able to run my apps on real calcs, I can safely say that Flash Apps are not in any way inherently slower than any other program utilizing the same API functions. If the program is poorly written, that's another issue -- but don't go falsely accusing all Flash Apps of being flawed.

so has anyone tried the radiolinks for that 89 that comment on their effictiveness and what program they used.

In fact I was accusing TI, since they are nearly the only one who make flash apps (I dind't tested the purchasable ones, though).
In fact is it not ti's flash studio wich is real crap ?
It would seem strange that TI engineers program so badly.

**Disclaimer** I did not write the SMG, so much of this is speculation.

You have to remember that the SMG is still pre-*beta* software. Its speed may be increased in later revisions.

It looks to me like the reson for the slowness of the SMG is because it is calculating all of the transformations that can be accomplished on each expression. Flash Apps are indeed not inherently slow, but remember that this *is* just a calculator, and *is* inherently slower than a Pentium-class computer. In my opinion, it is amazing what TI and HP have been able to accomplish on calculators.

The statistics and finance apps are not slow. Again, maybe slower than an equivalent on a computer, but not slow for a calculator. I can't speak for EE*Pro and ME*Pro, since I haven't used these.

Do you believe that the AMS is poorly written? I don't, and I believe that the TI Engineers are excellent coders. If you read through the SDK docs (or TIGCC docs), you will start to get a feeling for just how much is put into such a limited machine. I also believe that TI has been working hard to create a system that is open and extensible with the SDK.

I did not think ti was going to finish it?

I thought they said somwhere they did not plan to get any of those apps past early pre beta? Hope you're right though.

^----Following quote comes from the page in the URL up

"The intent of Concept APPS is to allow TI to share these products with our customers EARLY, for the purpose of receiving feedback regarding:

1. Whether or not you like the application at all.

2. Any suggestions you have that could improve the design of the application, making it easier to use, or including other functionality that would make it even more useful."

What I get from that is TI is releasing the SMG now so they can
a. decide if user interest is enough to warrant continued developing it.
b. ask users what features they would like to see in the SMG.

Perhaps this won't get out of concept app stage. That would be disappointing for me--I think it is a good idea.

i usually try every app for my ti89 in vti, is there any way i can upload a flashapp to vti?

     31 March 2001, 04:15 GMT

I Don't belive so.

No, Rusty did write for compatibility with flash apps.

The only way is to send it from an actual TI-89 to the VTI, either with a ROM dump, or (easier) by setting the VTI to communicate with your calculator (right-click, Enable Cable Link and select the right cable type) and to send it like you would do from a calculator to another.

Note that both of those methods will work only for applications which do NOT require a certificate (free applications).

Once a formula has been entered you can go through it's subexpressions in pretty print. These subexpressions being highlighted in boxes just like with the equation writer. So maybe ti will make an equation writer themselves?

The app is not that slow. It's just all the display operations: just look the help. The display routines of tifalsh studio must be poorly written.

This is way off topic, but would anyone happen to have to have AMS version 2.04? I hate 2.05 and I want to dongrade back to 2.04 so that all my programs will wokr again. ANd yes, I did e-mail ticares@ti.com but they have yet to respond. SO If anyone could possibly send me a copy to downgrade my calc. , please E-mail me.

right here. I got it from ti89zone.free.fr and they linked me to this site, a TI site:) I had 2.04 on my calc, but SMG doesn't show up on the flash apps screen there, so i am to 2.05, but 2.04 is on my hard-drive.

I should point out that you need AMS 2.05 to run this program; 2.04 won't work.

If I upgrade my TI from rom 2.03 to 2.05 will I loose all I've got? Would any applications I have not it stop working (I've got tons of stuff, the ebook reader, games, doorsos and so on...)
So what do you think?

I upgraded from 2.03 to 2.05 and I didn't lose any functionality. I have the ebook reader by Thomas Nussbaumer and many other games and programs. I dont use DoorsOS any more though. Tictex Explorer is vastly superior. Equation Writer 1.01 by EW works fine on 2.05 as well. The only difference Ive noticed is some more units in the units menu.

I think you have to back up your programs. They will get wiped. (FlashApps and archived stuff might be different.)
