I have a freeware calculator that I have spent about 3 months updating
and now have up on my website for download. I need user feedback on
usability, any bugs, suggested features, etc.

It does expression evaluation, programable with VB Scripting
language, does 2D (polar, cartesian and parametric) and 3D plotting,
Matrix manipulation, complex number math, 1-variable equation solving,
simultaneous equation solving (2x2 to 8x8), Integer math to 32000
places, 2D statistics with graphing and regression curve fitting, unit
conversions and geometric area/volume calculations. For documenting
calculations, it has a built in RTF editor, image editor, formula
illustrator and schematic capture module.

The design started out as an aid for engineers but has evolved more
into a learning tool for math students. The link is:

Any feedback would be most welcome. Thanks.

What a nice utility! Wish I had this when I took Calculus (or, was it when
Calculus took me?). Thanks for sharing.

Click and hold the mouse over the logo in the middle of the top and drag it
around.

I see no logo, but if I click and grab on the grey-shade at the top, it
moves.

when you get around to adding those missing functions, maybe you could
get your install system to set a install dir setting in the registry so
the code can find the help files in another partition/dir. figure those
VB apps get a VBA Applications key anyway.

nice calc, though!

The hyperbolic sine, cos, tan are in there but not their inverse. I will
add those.==================================

What I would really like to see are the COMPLEX hyperbolic functions.
Like -

Tanh( A + jB ) = X + jY

Look under Modules, the Complex Number Calculator. Hyperbolic
functions are already there.....

Could you also make it solar powered? Any good calculator these days HAS to
be solar powered. ;)

Overall its very impressive.

3 issues I can point to:

1. It ignores alt f4.
2. It can't deal with some screen resolutions, particularly lower
ones.
3. a) The expression inputs are command style rather than GUI like
windowns calc, and
b) its fussy about the exact format (spacing, requires use of
unnecessary brackets), consequently there is a problem:
c) it keeps rejecting expressions put in.

The solution would be to have it autoreformat the expressions before
calculating them, so that all the common alternatives were accepted.
For example, sin45 and sin 45 are rejected, it only accepts sin (45).
