GraphViewer 1.0.5

GraphViewer is a grafical 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...

Features
* You can enter any mathematical function you want to plot and evaluate
* You can zoom in/out and move the canvas infinitely
* The solutions (null points) of an equation can be calculated and shown
* Easy function input with the insert function command (list of commands).
* The first derivate can be shown
* You can calculate the local minima and maxima of the function
* The second derivate can be shown
* You can calculate the function inflection points
* Multiple functions can be plotted in different colors at once (see screenshots)
* 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 nullpoints, minima, maxima, inflection points... are automatically calculated)
* Build-in samples thow the possibilities and possible functions
* Calculate any function point up to 14 decimals.
* 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. These settings are saved, so you dont have to reset it each time.
* You can save your equations and add them to the samples library of the Graph Viewer. These samples are saved persistent, for as long as you want.
