A rabbit swims in a round pond with a radius of 1 with a constant speed . A tiger tries to catch the rabbit on the shore before the rabbit reaches to the shore. The tiger runs on the perimeter of the pond 4 times faster than the rabbit swims. The tiger can not swim, and runs the perimeter of the pond towards a point A of the shore in the following figure. If the rabbit is at the center of the pond, the tiger stops.

Now, find a way for a rabbit to reach to the shore
