Q)
(chatquestion)...44 A focal radius is the line segment from a point on a
hyperbola to one of the foci. The foci of a hyperbola are at
(4, 0) and (-4, 0). The difference in the lengths of the focal
radii from any point is always +6. Find the equation of the
hyperbola.
45 A hyperbola has its foci at (c, 0) and (-c, 0). The point
P(2, 4) is on the hyperbola and the focal radii (see Problem
44) from P are perpendicular. Find the equation of the
hyperbola....(Anyone? This no. 44 and 45)
