PocketPCFreeware : Math Xpander 3.0

Let's start with a little history: In 2000, Hewlett-Packard had a very advanced project for a new WindowsCE calculator. When I say very advanced, I am not kidding. Certains beta-testers were given the rights to functional prototypes. If you're interested, I recommend this link or this one. But don't expect too much. Well, you may be a little bit more frustrated when I tell you, HP couldn't decide between Linux and WindowsCE...
Math Xpander, the latest freeware, is a program that will let you believe you own this mythical HP prototype. It is available from the company who brought to light the geometric construction engine.
The program works like a library in which you can create elements by directly entering complex equations (derived, integrals, etc..), or by using 1 of the 4 integrated modules: curves, statistics, geometry, and notetaking. Each recorded entry can be edited or used again as you wish.
-the curve tracing tool is nothing new compared to any scientific calculator, it is only a large library of pre-defined funcions and a bluffing function which gives the equation for a curve drawn by hand.
- the geometric tool is one of the strong points of this program. It allows figures to be traced, but it also calculates and lets figures stay up-to-date with a click/drag function: verifying the Pythagore theory becomes child's play!
And now the program's weakest point: it cannot solve a pure algebraic problem - this limits any interest in this program if compared to the HP-48 emulators.
Note: The math keypad appear on the drop down menu but when you click on it you are taken to the basic math unless you change the following:
-run\windows\regsvrce.exe
-give the location of required dll, \windows\MathKeyPad.dll
-restart your computer.

I love this program! It took a lot of patience to figure out all of the functions, but once done it is a powerful graphing and geometric sketching tool. However, many bugs still remain and the user-experience is not "pleasant" which prevent it from recieving an 7/10. 6/10

A (large) problem with this programme is in its de-installation. A hard reset pf the PPC is needed to remove mathkeypad.dll completely.

Strange... Did you try to rename the DLL file first, then soft reset?
ianl (11-18-2006) - v3.0
That doesn't do it. According to the installation comments on the website, the "effects" of the dll are only removed by a hard reset. My best interpretation of "effects" is a large number of undocumented registry changes. Certainly, I had to hard reset to get rid of it. That possibility is one reason I always make an executable backup archive first
