Symbolic v1.2 [v1.4] for TI-83+
Posted by Eric on 17 December 2001, 05:44 GMT

Brandon Sterner of Detached Solutions has released his newest program, Symbolic v1.0 (v1.1 and v1.2 have since been released) for the TI-83+. This is a rather exciting program that allows users to symbolically differentiate and simplify algebraic expressions, functions that previously were reserved only for the TI-89/92/92+. Many other useful features are also included. Check out the Symbolic homepage for more information. It's always great to see people work on math-related programs...let's hope it continues.

Update (Eric): Symbolic v1.4 has now been released.

Anything .8xk is a TI83+ file.

Assuming you have an 83+, you may have to upgrade your OS before you can send this. Also, you can't open it in the program editor, you have to use the menus.

Has someone noticed that the inverse trigonometric functions return wrong answers?.I guess no one uses them anyway...Still, the app is very good, the differentiation a simplifying are very useful.

I just got an e-mail from Brandon Sterner telling me that he´s fixing the problem, so please don´t e-mail him about that. Just don´t use those. If you need to, use sin-1(1/x instead of csc-1(x, cos-1(1/x instead of sec-1(x ,and tan-1(1/x instead of cot(x (at least I think that´s how it´s done)

Version 1.3 is out now. You can find it at www.detacheds.com. This problem should be fixed among many others. These include:

1. problems with let() - Andrey Gorlin, Patrick Poon
2. optimized lots of things
3. safer memory management in implicit mult routines
4. period after delete all - Andrey Gorlin
5. inverse trig was wrong!!! - Andrey Gorlin
6. graphing sign - Andrey Gorlin
I now made it so that it threw the errow divide by 0
7. The grapher and table editor like this much more
uninstaller had problems with archives - AndreyGorlin
8. Graph marked dirty after symbolic is run

I also made a new token, numStr() this converts a real number to a string. Should make making BASIC programs easier. I'll update the documentation a little later. Thanks to everyone who emailed me bugs. Keep letting me know if bugs persist.

if 1.3 is out now, why does the webpage & .zip file say 1.4?

Ok I uploaded yet another bug fix. Version 1.4 is out now. As soon as I released v1.3, of course Kevin Barmish emails me about another bug with exponents.

If you're keeping count, that's five versions released in eight days.

Hehe yeah sorry about all the updates. I honestly thought the beta testing had caught all of the bugs. I used to give Patrick Davidson a hard time about his many updates on phoenix. I guess I just never had a big enough project to realize how much work source code that gets this big can be. Sorry Pat!

What about the ERR:VERSION problem? (If you try sending programs containing the new tokens to another TI-83 Plus which has Symbolic installed, the receiving calc says ERR:Version)

Yeah I'm still a little uncertain about what to do about this problem. I could write a link hook to take care of this but that would require me to make a 2 page app out of symbolic. Another possibility is to just write an external asm program you have to run immediately before sending files to another calc. The problem occurs when a file is marked with version FFh in the vat entry due to the new tokens surpassing TI's tgarbagecollect. Right now I'm leaning toward Michael Vincent's idea, a key hook that when ever the user enters the link menu, a routine converts all the version bytes to 00h. Look out for version 1.41 :)

Yea, in all my hacking I always thought writing a program to eliminate that err:version message would be a good Idea...I saw a lot of those weird tokens in my hacking days...If you are interested in hacking, click the link.
