An ant of negligible dimensions starts at the origin (0,0) of the standard twodimensional
rectangular coordinate system. The ant walks one unit right, then onehalf
unit up, then
1/4 unit left, then 1/8 unit down, etc. In each move, it always turns counterclockwise
at
a 90 degree angle and goes half the distance it went on the previous move. Which point
(x,y) in the xyplane
is the ant approaching in its spiraling journey?
