Hi,

I've been using my HP50g for a little less than a week, and I'm on the
process of getting acquainted with it. I thought of a feature that is
not built-in, and was wondering whether there is a program or a library
that would let me do it.

What is the best way to create some sort of equation collection? I like
the default equation library, but unfortunately it is not expandable (or
is it?). I would want to save useful formulas for later use in an easily
accessible place.

Some features that initially come to mind are as follows:
* being able to categorize equations based on their topic (EE, physics
etc...)
* store the equation in EQ with one soft-key so that I can then use the
various solvers to play with them.
* maybe add a title and a memo to each equation to remind myself of how
and when to use it...

Do you know if something like this exists? I looked it up on hpcalc.org
but couldn't find any decent solution.

Thanks,
Berk

That is the one I'm partial to. Of course, I wrote it so you'd expect
that. ;-) I am the first to admit there are other more advanced ones.
Mine was designed for quick easy access in minimum space (its only
1.5k). You may like it. I'll let other extol the virtues of
additional programs.

You can do things like solve single equations, solve entire folders of
equations at once, even recursively clean out your equation folder of
your variables created during solving (you complained about that a few
days ago).

Hi Berk,

Wolfgang Rautenberg's EQL+ for hp 49g+ works
fine with hp 50g (tested with ROM 2.09).
EQL+ is much shorter, than the "non-official?" one from HP
and can be extended with your own equations.
It does not support units (like the one from HP).

Tim I took a look at your libary. I tryied a simple V=I*R calc, and it
reverted to variables such as dw and dt. I cant work out how it knew to
revert to such and how do we force it to use I and R?

Ok I worked out that I had the "other" equations stored lol, but how do
I toggle this time, would be good to get this working properly.
