Draw cartesian graphs (i.e. in X and Y), a percent % key in SCI, STA and FIN modes, inverse functions for SQR ROOT CUBE C.ROOT %, reorganisation of the menu, smaller memory footprint (approx 45kbyte - was 65kbyte) Looks very impressive (albeit perhaps overkill for me). In 2003, Bob Hepple kindly made the C++ source code available (should make a good example of how to do a large Epoc program). Marcus von Cube kindly compiled without the nag screens www.mvcsys.de Former Shareware £15 US$21, A$30, or trial for four weeks. PocketIQ formerly http://sedumi.freeshell.org/psion//index.html

Formulary

Flexible symbol calculator, can also be used as a general units calculator for which any list of constants can be entered. Also generates plots. Seems to be getting more extensive. Peter von Walter. Shareware $10 and a Lite freeware version also. www.physi.uni-heidelberg.de/~vwalter/my/FORMULARY/Formulary.html

Graph32

by Nicolas Piguet - will help you analyse complex mathematical functions and includes features you would only normally get on a purpose-built graphical calculator. It's quite simply the most advanced EPOC tool available for this type of mathematics. Try www.freepoc.de

Grapher function graphing

Jamie Shotton's shareware program does Cartesian and Polar graphing, graph tracing, etc. Formerly www.geocities.com/SiliconValley/Bay/6740

HART computer algebra system

HartMath which is written in Java 1.1 and needs a Java virtual machine on EPOC32. Formerly www.hartmath.de/index_en.html

MathDraw

There is an application called MathDraw (available from TUCOWS) which is essentially a text-based version of M$ Equation Editor, converting your text description into maths format (i.e. fractions appear with the top number directly over the bottom number). These can be exported as Sketch files and inserted in the Word app. You can't have superscripts and subscripts on the same character, preceding subscripts or superscripts (like in chemistry equations for isotopes, etc), and the '-' (negative sign) preceding a superscript only displays the '-' character in the superscript. Takes a bit of getting used to but it is only 9kb in size and free, so what do you lose by trying? MathDraw from Niklas Larsson. You could download at nicbit.cjb.net

MathsHelp

Gary Ewer. v5. Time additions in hours minutes and seconds. Degrees to radians. Simultaneous equations with 2 or 3 unknowns. Quadratic equations. Children starting algebra might enjoy it. www.come.to/prosoft

Doesn't work from drive E: Tested version 5.2 dated 1998. US$15 shareware. Pretty cute, but I can do mental arithmetic, and the unregistered version is annoying. www.kylom.com

Multifunction RPN Calculator

Derek Johnson, shareware V1.6, #10, US$16. Like HP16C. Hex, octal and binary modes, list ASCII, statistical and financial functions, time calculations, logical functions, lots more, good help files. Should be great for anyone who misses their HP calculator. Formerly at www.freeuk.net/decca

Science and Technology

Biotechnology Glossary

Robbe Wunschiers. The glossary contains 568 entries of the world of biotechnology (version 1.2). Download the Psion 5 database file (zipped, 39kb) at the PsionPlace. The database is also available in the TomeRaider database format (Download: biotech.tr, 48kb). http://mitglied.lycos.de/roebbe/

Buffer Calculator

Buffers are intensively used in Chemistry, Biochemistry and molecular biology to maintain a preset pH value in a aqueous solution. Yet, the buffer properties are influenced by not only by the buffer substance but as well by the temperature, the ionic strength of the solution and other parameters. THE REAL BUFFER takes this into consideration and calculates the amount of buffer substance to use and how to titrate. It uses a database containing the most common buffer substances used, and which can be altered by the user. members.tripod.de/roebbe/
