1. curvedrawing_3main.cs
   
2. curvedrawing_3frame.cs
   
3. curvedrawing_3logic.cs
   

To run the program on linux please run the follow in the terminal to create the curvedrawing_3logic.dll:

  $ mcs -target:library curvedrawing_3logic.cs -r:System.Drawing.dll -out:curvedrawing_3logic.dll

After, run the following in the terminal to create the curvedrawing_3frame.dll:

  $ mcs -target:library curvedrawing_3frame.cs -r:System.Windows.Forms.dll -r:System.Drawing.dll -r:curvedrawing_3logic.dll -

Also, run the following to create an .exe file:

  $ mcs curvedrawing_3main.cs -r:System.Windows.Forms.dll -r:System.Drawing.dll -r:curvedrawing_3frame.dll -r:curvedrawing_3logic.dll -out:curvedrawing3.exe

Finally, execute the following:

  $ ./curvedrawing3.exe

or run the run.sh file with the command

  $ sh run.sh

1. The C# coordinate system and Math coordinate system.
2. Conversion between C# coordinates and Math coordinates.
3. The scale factor that relates the two types of coordinates.
4. Equations in polar coordinates; equations in rectangular coordinates.
5. How to add consant to the current image without destroying the existing content.

The program will have a UI that display a panel structure of buttons (Start, Pause/Resume/ Exit). It also displays the X and Y coordinates values showned in mathematical coordiantes of the point of the ball pen as it draws the curve.
