Question: Rotation of letter L about the y-axis in 2D only - plot not working


   I've asked a similar question before, and got the letters to rotate in 3D using the rotate command.  The resulting size in a 3D plot is relatively small..  The program gives a plotted letter L.  I wish to get some animation of it being rotated about the y-axis - but remaining in 2D.  ie looking at the letter it appears to be rotating.  To do thisI have multiplied the x-coords by the cosine of the angle of rotation.   

   In the for loop towards the end of the program there is a variable c1 which is incremented by one in the loop - yet it remains at 2, regardless of the angle increments.   Why is that?

  Again, any help or comments much appreciated.
