You have a modern, Java compatible mobile phone and wouldn’t it be handy if you could use your mobile to plot functions or use as an advanced scientific calculator? Well, GraphViewer is a graphical calculator that you can download and install on your mobile phone. With GraphViewer you can plot equations using the build-in functions, calculate its derivate, show a table with the functions critical points and even many more features.

Features:

- The solutions (null points) of an equation will be shown
- The first and second derivate can be shown
- Show the integral of a function
- You can calculate the local minima and maxima of the function
- You can calculate the function inflection points
- The intersection points of the different equations are calculated and can be shown
- You can interactively evaluate the functions at their critical points
- You can show a function table with the function coordinates at its critical points
(So the null points, minima, maxima, inflection points… are automatically calculated)
- Build-in samples show the possibilities of all functions
- Calculate any function point up to 12 decimals.
- Multiple functions can be plotted in different colors at once
- In the settings you can set the internal precision, so you can choose between low precision (fast) or high precision (slow), depending on the speed of your mobile.
- You can save your equations and add them to the samples library of the Graph Viewer.

Change Log:

* Totaly renewed calculator with easy function input
* You can solve equations in x using the calculator. So if you would enter “5x-3=7″ then the solution would be x=2.
* Parametric equations are possible in three dimensions as well, this makes it possible to plot a sphere, a spiral… You should enter the parametric equation into the form of “x=f(t,u);y=f(t,u);z=f(t,u)” so for a spiral this would be “x=tsin(t);y=u;z=tcos(t)”. (*)
* Renewed GraphViewer application icon that looks way smoother (Thanks to Chris Katopodis)
* Touchscreen icons to reset zoom level to 100% and to zoom horizontally (when you select the x icon, the zoom magnifiers will work in the x direction only)
* Nepalese and Finnish translations added
