A rainbow trout is an extremely cautious fish constantly monitoring the surface of the stream looking for both food and predators. A trout escapes immediately, once noticing something suspicious, like a fisherman caring his fishing gears. Assuming that the height of the river bank is 1m, what is the maximum height of the fisherman, such that he would be "invisible" for a trout that is at the distance d=2m from the fisherman.
