Introduction

Jasymca has been developed for teaching mathematics, especially to facilitate a fast and easy entrance to computer mathematics. One of the main obstacles are pocket calculators, which prevent many students from using computers for math. Pocket calculaters are cheap and portable, while CAS-programs are often expensive and always require at least a laptop to run. Jasymca is free software and runs on almost any system equipped with a microprocessor: from mobile phones and pdas to windows/linux/macos computers, even on game consoles or internet routers.

Jasymca 2.0 is based on Jasymca 1.01 [1] with significant extensions and improvements. Apart from the new grammar (Jasymca 1.01 was Maxima [7] - oriented), matrix and plotfunktionen were added, as well as the parser and compiler completely rewritten. The user interface defaults to a style reminiscent of Octave [4], Matlab [5] and SciLab [6], without copying each detail. Users of either of these programs should have no problems using Jasymca, and, for the sake of teaching, vice versa. The main extension to these programs is the seamless integration of symbolic calculations, which do not require special commands.

The user interface can be switched to GNU-Maxima-style, which is more conveniant for some problems, see chapter 3 for details.

Chapter 2 of this document is a tutorial with examples and exercises, partially taken from our introductory Computer-Mathcourse for engineering students. Most examples can be solved by the applet at the Jasymca-homepage [8], and do not require any installation. The next chapter briefly explains the alternative Maxima-mode. An overview and reference to all commands, functions and options follows (chapter 4), and the last chapter ( 5) deals with technicalities of installing Jasymca on computers and mobile devices.
