You have always considered maths as a complicated and boring thing? You were wondering why you had to buy a standalone graphical calculator even when you have your Psion? Now discover another side of this science, bring it to a new dimension. Graph32 - by Nicolas Piguet - makes one more step towards today's graphical calculator standard with it's new 3D surfaces functionality.

But that's not all, Graph32 now provides an even more powerful support for 2 dimensional functions, while staying as easy to use as before. And even better, you can now load and use additional plugins into Graph32 to bring new functionality to it. You can now even program your own plugin to make sure Graph32 does what you want it to do!

Features include:-

• Support for 4 types of functions (Cartesian, Parametric, Polar, Inductive)
• Full function analysis tools for cartesian functions
• Supports derivative and second derivative plotting for cartesian functions
• 'Colour mode' operation on both colour and monochrome machines
• Cursor trace mode option - allowing you to find the value of any function for a specific variable value
• Includes simultaneous and quadratics solver
• Default physical constants (g, G, ce, me, NA) and customisable constants
• English and French versions included
• Support for 3 kind of 3D surfaces, along with 3 paiting styles and their trace mode.

New in version 2.21:

• Support for up to 5 plugins
• Support for hyperbolic and inverse hyperbolic functions as well as co-tangent
