Perhaps a picture will help...

http://cnw.com/~bkb/Eu/chord.PNG (an arc is similar)

xStart and yStart are arbitrary points that define a line (radial1) from 
the center of the bounding box (that defines your ellipse)... this is 
the start of your arc/chord.  xEnd and yEnd define radial2 and where it 
intersects with the ellipse is the end point of your arc/chord.

At least that's the way MS defines it... I usually just play with the 
functions to understand them better.
