Some comets, such as Hailey's Comet, are a permanent part of the solar system, traveling in elliptical orbits around the sun. Others pass through the solar system only once, following a hyperbolic path with the sun at a focus. The figure shows the path of such a comet. Find an equation for the path, assuming that the closest the comet comes to the sun is 
mi, and that the path the comet was taking before it neared the solar system is at a right angle to the path it continues on after leaving the solar
system.
