Simultaneous Equation Solver FLASH App
Posted by Eric on 19 November 2001, 21:59 GMT

TI has released a new FLASH application: Simultaneous Equation Solver for the TI-89 and TI-92+ (click link to login, click again to view page). Basically, it's a little application for you lazy types who don't want to use solve() or rref() for some odd reason. It's free, so go check it out. Thanks to the hordes who emailed me with the news.

I already wrote a BASIC program for the 89 to do this- put in a matrix of coefficients, and it gives you the solution, formatted pretty and all.

Why does TI keep releasing apps that don't do anything the calculator doesn't already?

Exactly! They must have run out of ideas and think that by releasing the same thing with a different title may work...

I hope they release the organizer APP too.. and I hope it's free!! You never know what TI can do!

I created my own simultaneous equation solver also, which oddly resembles "Simult" for the 85/86

bdesham, how good is your program, so I can compare them :)

Put in the matrix, it tells you how many dimensions the system is in (i.e., how many rows there are), and the solution in the format (x,y) or (x,y,z) or whatever format the solution needs to be in.

Want to swap programs and compare?

Sure, send yours to arnpoly@hotmail.com, and I'll send you mine.

Well post our findings here...

How is it different from the TI-89/92Plus simult()?

Simple, the built in simult on the 89/92+ needs matrices to operate, and my program just needs the coefficients on the x and y terms (or however many you need, my prog supports ones of limitless size :)). It processes the coefficients and compiles them into matrices, making the process easier for the user. I hope that made sense.

du bist ein affe - that's all the german i know (but i had to double check with smarterchild (side-note.. i HIGHLY recomend everyone adding SmarterChild to their buddy list... smartest robot you'll ever talk to (movie times, translator, weather.. etc...)

who is that? robot? eh? I put 'smarterchild' on my buddy list for GAIM, and it has a little smiley face beside it, instead of the blue/orange aim, or the blue AOL.

Well, AOL's IM client for Linux <em>really</em> sucked, so I looked around for another one...

Yes, it sucks indeed.

What is GAIM? Where did you find it? Are you gonna eat that?

Quack.

you can find gaim at http://gaim.sourceforge.net/ It's a really nice AIM client for Linux... although the version I am using doesn't let you read a person's away message when you get their info.

It's kinda spooky. I like to say weird stuff to it, it's fun. For example...

How old are you?
"I was born on June 19th, 2001, so I'm still real young!"

Where are you?
"I live in a clean room at a high-tech hosting facility in California."

Sex?
"*sigh* Why is it that all humans eventually tell me things about that?"

F*&! you!!!
"Whoa. I haven't heard language like that since the last Chris Rock special."

There's 5 total that I know of... SmarterChild, GooglyMinotaur (a Radiohead fanbot), LindsayBuddy (a Lindsay Pagano fanbot), AgentBaseball (a baseball fanbot), and TheSportingNews (an NFL newsbot) They're spooooooky.

I know it's difficult to realize it, but we all have problems that we need to learn to cope with. This guy here has some MAJOR problems. That is all.

Remember, there are no stupid questions, just stupid people.

More of the same BS from the eunuuchs at TI. This may be OT but (and those who followed my posts when I used to frequent this site know that this sentiment has been building for some time) the tail has really come to wag the dog at that company--the bean counters and useless management types must be directing the calculator division.

It smells like this program was written for technophobic grade-school algebra teachers. A really dumbed down front end for rref() is all this is. But then again the entire calculator division at TI has targeted itself at this market--educators as opposed to calculator users!

The website has become virtually useless. Their machines are worse. The 89 is a powerful multipurpose machine with a killer CAS and the potential for expandability ad nauseum. There were many far more useful things TI could have developed...integral transforms, a real 3-d engine, a vector calculus toolbox, etc, etc. I doubt I was the only user ever to harass them with my feature requests.

HP, on the other hand (that is until the recent suspension of development) listened to its users. Heck, they even hired them to do the HP48+ and the HP49. Now they dominate the market of technical professionals. With the 89 TI could have at least made inroads into that market, but they castrated the machine at birth.
~~~~~~~~~~~~~~~~~~~~
When I got into New Orleans this August my calculator (along with other things, incl about $1000 of hard-earned cash) were stolen from my vehicle in overnight parking. I gave it a lot of thought, and decided that I was going to replace my 89 with an HP49 (insurance let me get away with it--I got one dirt cheap). Turns out the thing, new in the package, didn't work (it would not shut off).

I finally recieved the replacement today (HP suffers from their own version of fubar, mostly having to do with old vs new 49s)

This machine is wonderful! Many of the feature requests I put in for the 89 are implemented, and the HP user community writes more useful math and science software. (Needless to say I am no longer writing 89 math software...)

My recommendation for those who are tired of TI's overpowered educational devices: vote with your feet and your money and buy HPs. Collegiate or higher-level math, engineering, and science students may be nowhere near the majority of TI's users, and are possibly not even the majority of 89 users, but with regard to the 89 we should be a sizable enough market for TI to take notice. It's time that some competiton was put back into the high-end calculator market.

Whew! That was a rant!
