Posted:
Feb 10, 2009 9:01 PM


I have two point I need get middle point from the segment of these two point. A(8,(2/3)pi) and B(6,pi/3).
My Plan:
1. Transform A and B to Cartesian system 2. Get the middle point P((x1 + x2)/2, (y1 + y2)/2) 3. Transform P to polar system
but I not be able get correct answer... anyone have some suggest ? I think my error is item 1, sample my A point in Cartesian system is (4sqrt3,4)it is correct ?
thanks a lot,
Alex
