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,
