Math Fact Tuesday! More of a puzzle, but if I give you the answer it'll become a fact, right?? This puzzle (credited to Martin Gardner) can be stated as follows (text source): We are in a rowboat in the center of a circular lake. On the edge of the lake is a mean goblin who wants to eat us; and if he catches us, he will do so!! The goblin can't swim and won't go into the lake (and doesn't have a boat), but he can run K times as fast as we can row. We, however, can run significantly faster than the goblin can, so if we are able to reach a point at the edge of the lake without the goblin being there, then we will be able to escape. Question 1a: For K = 1, is there a strategy we can use to escape? Question 1b: What about K = 3? or K = pi? or K = 4? or K = 5? Question 2: What is the best possible value of T so that:
if K
