ACalc 0.21
ACalc is a scientific calculator using double precision math with 15 digits of display. more>>
Formula entry is algebraic (EMDAS). Usage is natural and intuitive, with a simple main window consisting of number -operation- and function keys.
Enhancements:
- Argument checking for arctanh is now correct.
- Tan of values close to pi/2 and 3pi/2 or their multiples now reports the error "tan infinite?"
- Pressing on the EXE button after editing the old input expression sometimes clears the expression in v0.20. In v0.21 the newly edited expression in evaluated, as expected.

Sketch2Go 0.7.1
Sketch2Go is an excellent and free program encouraging visual exploration of phenomena by providing qualitative indication of the ways in which the sketch drawn by the user changes. more>> Sketch2Go 0.7.1 is an excellent and free program encouraging visual exploration of phenomena by providing qualitative indication of the ways in which the sketch drawn by the user changes. The sketch is a diagrammatic representation that attempts to help the viewer focus on the principles rather than on tedious details of the represented phenomenon. Phenomenon can refer to processes outside of mathematics (e.g., physical temporal phenomena) or to mathematical phenomena (e.g., a function with three extrema). Moving students beyond plotting and reading points to interpreting the global meaning of graphs and the functional relationships that they describe has been identified as a major goal of mathematics education.
Tools like Sketch2Go enable the bypassing of algebraic symbols as the only channel into mathematical representation, and motivate students to experiment with a given situation, analyze it, and reflect upon it, even when the situation is too complicated for them to approach symbolically. The visual analysis that emerges from work with such tools is different from that which arises from work with algebraic symbols or numerical tables.
Major Features:
- Sketch2Go is a qualitative graphing tool. Graphs are sketched using seven icons representing constant, increasing, and decreasing functions that change at constant, increasing, or decreasing rates. It is based on original R&D carried out by Schwartz and Yerushalmy (1995) and Shternberg & Yerushalmy (2001), who propose an intermediate bridging representation based on the function and its vocabulary. The seven graphic icons describe the change in both the function and its rate of change. Sketch2Go is a version of the Qualitative Derivative Grapher programmed by Alexander Zilber for CET (Centre for Educational Technology).
- Mathematical modeling cannot be fully accomplished by this qualitative sign system of constant, increasing, and decreasing functions. But the set of seven signs supports forming a mathematical construction with language developed from acquaintance with physical scenarios, helping lay the foundations of learning pre-calculus and calculus. Sketch2Go supports the abstraction of everyday phenomena using a small set of mathematical signs that can be manipulated on screen as semi-concrete objects.
Requirements:
- Java Enabled (J2ME) Phone - Profile/MIDP-2.0 Configuration/CLDC-1.1
- Screen Resolution: 128 x 96 and above

Currency 4.2
Currency features 146 currencies, the 13 old Euro cuurencies and 10 fully configurable entries for user defined currencies or trade quantities. more>>
A fully configurable display enables the synchronous conversion of up to 8 simulataneous currencies.
The exchange rate date is stored for each individual currency, providing an easy mechanism for assessing the validity period of critical rates.
A visual warning marks outdated rates. A fully functional algebraic calculator and a single button tax adder / subtractor simplify common arithmetic operations.
The exchange rates can be updated by downloading a small daily updated currency database (cupdate.pdb) and syncing it to your PalmOS device.
The update is done daily around 18:00/18:30 UTC with the spot exchange rates for 146 currencies.
The java conduit from Tim Endres used in previous Currency versions to automate the update of the currency database has been adapted to the current versions of HotSync.
It is also included in the zip file and contains a fix to make java based conduits work with HotSync 6.0.x.
