Description
Pi Cubed is a visual math application designed from the ground up for a touch-based interface. Unlike traditional calculators, Pi Cubed lets you construct, typeset, and instantly evaluate mathematical expressions using an interactive menu system. The use of the entire screen, combined with the capability to lay out equations as they would be written on a piece of paper, makes even complex calculations easy to follow. Common touch gestures, like pinch-zooming and touch-based panning, enhance the entry and editing process.
A diverse range of mathematical operations are supported, including logarithms, trigonometric functions, arbitrary roots, exponents, and factorials.
Calculations can be stored within the internal database for later reference or editing. Also present within this database are over 150 built-in 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.
Equations can be sent via email in LaTeX format for inclusion in papers or other publications.
Detailed information on all features is present within the in-application manual. Video walkthroughs and the full content of this manual can be found at our product web page.
What's New in Version 1.11
In-application email of equations has been added. Equations can be copied to the system clipboard for pasting elsewhere. When inserting a new operation, the selection shifts to the newly inserted element to ease calculation entry. Crashing bugs involving custom variable entry and insertion of untitled categories have been fixed. Custom variables used as equation answers are now saved properly.
Customer Reviews
Great potential, needs to enable constants and dual- symbolic and numeric -representations.
As one who teaches physics I like the pi cubed concept very much. Its utility would be greatly enhanced by two key advances. First, one should be able to construct a symbolic formula, and then substitute in numerical values for the symbols without losing the symbolic representation. Being able to flip back and forth between the two would be great. Second, one *must* be able to store constants such as hbar, Boltzman's constant, and so on in the library, then use them symbolically in a formula wherein their numerical value would be used for a calculation.
Innovative and useful
As a physics major, I have to say that I've been looking for an app like this. Don't expect it to replace your calculator - use it to play around with equations like you would on paper, and get real-time results when you put in numbers. A few features are really needed before it's perfect, but I think the devs are on that already.
Needs radians desperately! Other good features would be a memory for results, ability to add your own constants, and symbolic manipulation of equations (right now if you make an eqn, you can only put numbers in). Also the hyperbolic trig functions would be nice.
Keep up the good work!
Needs a "new" button
The interface is a bit tough to get used to and less intuitive than what one might expect from an app like this. Also, unless I'm missing something, which is possible since the app is a little counter-intuitive, there is no way to start a new equation other than to "back out" of what you've just done. Moving from a pre-programmed equation to one of your own making can be a drag. It would be good to have a "new equation" button on the main screen so you could start from scratch easily.
