What's new in v1.3

Changed: Minor issue with export of graphic

Description

From the listing uploaded by “appupdater”.

The app 2D-Graphs offers the graphical representation of functional graphs of type f(x) or (x(t),y(t)). It comprises the computation of intersections, zeroes and extrema. One specialty is the development of the integral definition with a number of methods. Among these are upper and lower sums, trapeze and Simpson method, showing an approximation of the integral value. In addition the area betwenn two graphs can be calculated. For each graph, you may define a location, where the programme calculates the slope and draws the corresponding tangent. The functional type (x(t),y(t)) in parametric form can be used to visualize paths. All computational results are shown in the scrollable text area at the bottom. There are 4 lines provided to allow descriptions, 2 at the top and 2 at the bottom of the graphical area. You can save the actual session as a file and load it later. The option to export the graphic as png completes the capabilities of the programme.

2D-Graphs APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the 2D-Graphs APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 73b5de69effe3d3742fe941cefc84ff6.
