Math Xpander

Math Xpander™ is an application that resulted from investigations within laboratories at Hewlett Packard. It supports real time interactions between users and mathematical objects with a stylus in multiple representations: graphic, symbolic, and numeric. Saltire Software contributed a computational engine that supports geometric constructions in the application.

Platforms

Math Xpander runs on Pocket PC devices with either the sh3 processor (e.g. HP Jornada 540 series), the MIPS processor (e.g. Compaq Aero 1550 series, Casio Casiopeia), or the ARM processor (Compaq iPaq).

e-Lessons

There are two e-Lessons available for download. They run on the same Pocket PC devices that Math Xpander runs on, except that FunctionComp is not available for the ARM processor (iPaq). The e-Lessons are:

FunctionComp: explores composition of functions

PeriodicTable: explores the periodic table of the elements

PC Emulation

Math Xpander, and the two e-Lessons, may be run on a Windows NT or Windows 2000 PC emulating a Pocket PC device. To do so, you'll need to download and install the Microsoft eMbedded Visual Tools 3.0. This is a rather large (304MB download) package. Once you've installed the development tools, you'll need to install the Math Xpander emulator binaries. You can also run the two e-Lessons under emulation:

Disclaimer

The Math Xpander and e-Lesson software is offered "as-is" with no user support, beyond that found in the User's Guide and online help. There are known "bugs" in the software, and users should not expect that any attempt will be made to fix them. Users must read the license agreement before installing the software.
