In submarine location problems, it is often important to nd a submarine's closest point of approach to a sonobuoy (a sound detector). Suppose that a submarine travels along a parabolic path y = $2 and the sonobuoy is at position (2, 0.5). It has been known that the value of :1: needed to minimize the distance between the submarine and the buoy must satisfy the following equation Use Newton's Method to find a solution to the equation x = 1 correct up to 9 decimal places. 1+ x2
