**bobpursley**, Tuesday, September 6, 2011 at 11:24amdistance=5/6 * 2PI *r

displacement: final point-initial point

Displacement= r@5/6 *360 - r@0

so in circular coordinates, displacement is r@300-r@0

Now in rectangular coordinates

displcement=r (sin60 N + cos60W)-r(sin0 N + cos0 W)

and you can work that out.
