Hi guys ! This is my problem! I want to create a pie chart… . I used  
\_root.a=Math.cos(0\*Math.PI/180)_radius;  
\_root.b=Math.sin(0_Math.PI/180)_radius;  
for my first point  
and  
\_root.c=Math.cos(degrees_Math.PI/180)_radius;  
\_root.d=Math.sin(degrees_Math.PI/180)\*radius;  
for the second point.  
so my problem is that i cant calculate the control points to join the 2 points?  
anybody knoes ???
