Function Inspector Web online

I Just added a new Page "Function Inspector Web" to this blog which contains a link the Java Applet of Function Inspector Web.
This is the version that I published as an *.exe file a few days ago.

Please remember that you will need Java in order to run this applet. You will find a download link on this page, too.

Function Inspector coming to Desktops!

I just renamed the title of this blog from "Android-Blog" to "Dev-Blog" because I just finished a very early preview of a Desktop version of Function Inspector:

A very, very early build of Function Inspector Web which will probably be a Java applet in the future.

In fact, this is my very first useful (to some extend) software that is not written for Android. Of course, I was able to reuse all of the functionality because both is written in Java.

As you can see on the screenshot, I chose a layout that is quite similar to how the Android app is structured.

Those are the things that are working:

• Draw one function: It can draw any function entered in the huge text field. It should also recognize discontinuities like in tan(x)
• Pan and zoom: Just drag the area and use your mouse wheel to zoom
• Display roots, extrema and inflection points: It does not return the coordinates, though 

Everything else just won't do anything ;)

I am planning to create a dedicated website and upload it as a Java Applet. For now it is available for you to test it as a Windows *.exe file:

Function Inspector 2.8

tan(x) and 1/x: Function Inspector 2.8
recognizes asymptotes and eliminates
vertical lines

I just published an update to Function Inspector which includes the following changes:

• Recognition of Asymptotes: functions like tan(x) or 1/x are no longer drawn with a vertical line
• No more haptic feedback for the keyboard: A user complained about it and I decided that it is unnecessary. If you found this feature useful, please let me know!
• Background work: I improved the existing code which should not affect the look and feel that you are used to. If it does, please let me know!

As you can see, Function Inspector is going towards its 3.0 release which will be a major upgrade as I am planning to make some changes to the UI as well as to improve the functionality.

But that's it for now, I hope you'll enjoy the update ;)

Function Inspector 2.7.1

This is a very minor but convenient update:
When the function input menu is opened, the first empty input box is focussed automatically, so you don't have to click in it!

Other than that I've been working on improving the existing code which is hard work that you don't notice, but it might speed up future updates ;)
