Sunset Lake Software today announces the release of Pi Cubed Lite, a free version of its Pi Cubed visual math application for iPhone and iPod touch. Pi Cubed uses an interactive math system that has been designed from the ground up for a touch-based interface. Unlike traditional calculators, Pi Cubed lets you construct mathematical expressions, using an interactive menu system, which are then typeset and evaluated instantly.
Because the full utility of this novel calculation approach is best experienced, rather than described, the free Pi Cubed Lite has been created to introduce more users to the power of this system. The free Lite version has all of the calculation capabilities of the full application, including a diverse range of supported mathematical operations such as logarithms, trigonometric functions, and arbitrary roots.
Also included in the full version is a built-in database of over 150 equations, representing fields that range from finances to fluid mechanics. You can use these equations (with fully annotated variables) for a quick reminder, or you can enter numerical values and directly evaluate the equations.
Finally, the full version has the ability to export user-defined equations in plain text or LaTeX formats, as well as to the external application Grafly for plotting.
Pi Cubed Lite is free, and can be downloaded from the iTunes App Store. Pi Cubed for iPhone and iPod touch is available for $9.99 (USD).
