This app is a function plotter for your system.
You can easily enter a function and then the app will plot the graph and show you the basic results of a curve sketching. I want to create a clear app which gives you a fast overview of the function.
Additionally to normal functions the app also supports functions with complex numbers, functions in a three-dimensional space, functions in a four-dimensional space, functions in parametric equation, functions in a polar coordinate system, functions in a spherical coordinate system and functions in a cylindrical coordinate system.
This app is also available for Windows Phone in a lot of countries.
Have fun.
