EQW v1.00 Released
Posted by Eric on 4 March 2001, 19:48 GMT

Since I'm not much of a gamer myself, it's always nice to see someone using calculators' capabilities to do... (drumroll, please) math! A Dane by the name of E.W. has released EQW v1.00 for the TI-89 and TI-92+. This is a graphical equation editor that can be used to create and edit equations graphically instead of on the command line. Quite useful for long, obfuscated equations, as you might imagine. And there's more, too: you can also call EQW to use in TI-BASIC programs.

The program is quite huge, and its documentation is one of the most comprehensive I've ever seen. Download it and find more information from its home page.

Wow!!! Great job. I'm really impressed. I'll definately keep this one on the calc.
Thanks.

Wow! Thanks to Lar's RPN and now this, I no longer need to consider getting an HP-49! Thanks for the great work!

Question:
Why would you ever consider buyying that ugly piece of crap!?!?!?

Because it has RPN and an equation writer (and, in my opinion, a better menu system)... :)

Where did you get Lar's RPN, there are a few around ticalc.org but none that are really good, I think I saw one somewhere that was really good.

Go to the download area of scs.calc.org. Also there is the alchemistry package which has disapeared from ticalc's archive.

I highly recommend this program to everyone. It is a must-have program! I've really enjoyed working with it. Doug has (as usual) done a fantastic job with the documentation.

This is really magnificent.

And at the risk of being called a plugger I will say that I wrote a package of shortcut programs for the 89 that will allow people to use this program (or any other for that matter) from any application in tios. It is in the misc programs section and is titled shortcuts.

I have to agree. I used Sam's shortcut program about 15 minutes after I got EQW. Thanks to EQW's emulation of the commandline (it's hidden, so you don't see it) I can run all my programs from it too. I haven't seen my home screen for two days now!

I was one of the Beta testers for the EQW, and I'm pleased to see everyone is happy with it. E W really deserves to take a bow.

Why are the files shown as being on ticalc.org if you cannot download them from there?

For once I'm impressed with something around here :-) . (Not that I've done anything myself.) This is a neat and actually useful program for those who use the symbolic manipulation capabilities on complicated expressions. It's good to see that there are other people who are interested in expanding the utility of the calculator as a calculator and not as a gameboy.

On an unrelated note I am seeking assistance on a perhaps equally ambitious project that I'm going to start over the summer:

A real 3-D plot engine FlashApp for the 89 and 92+, done with TI's SDK. The basic idea is to have something that will plot a point in a 3-dimensional "space" and then to build up a library of functions callable from the command line/TI-Basic to draw lines, parametric wireframe surfaces, space curves, etc.

Artraze Carthetus is also working on a 3D plotter (see URL above). Maybe the two of you could work together.

coincidently, I posted similar idea this summer. I am working with another person on this, and have come up with a program that plots 3d vector functions. If you want a copy of it, email me at bhedtke55@hotmail.com

AWESOME!! One of the best math programs I've seen for the TI-89. Makes equation making/editing a snap. Takes a little getting used to; it complains when using parenthesis, but other than that it's a big improvement over making a large equation from the command line. Thanks a lot!

I most definately must agree with everyone here! The prog is stable, functional and overall nicelooking :)
Some minor things could be changed/included, but it really like it!
