GraphViewer - 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 built-in functions, calculate its derivate, show a table with the functions critical points and even many more 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.

What's New in This Release:

Equations can be given in one of the following forms:

· Parametric equation: x=tsin(t);y=tcos(t)
· Polar equation: r=cos(4t)
· Cartesian equation in x and y: x^2+y^2=100
· Cartesian equation in x: y=sqrt(100-x^2)

Touch Screen Calculator Touch Calc 60, the scientific calculator is now available in a whole new avatar

Solve2Go Solve2Go - supports solving equations and inequalities by means of conjectures based on visual thinking. Conjectures can be refuted or supported by examples provided by the tool, and should be proved using symbolic manipulations on paper.
Equations: when we want to know for which values of x the two functions are equal
