BAB    4              HYPERBOLA




                                                       IV.        Definition and General equation of
                                                           Hyperbola
                                                           Point A is 3 units of distance from point F'.
                                                           Point A is 8 units away from point F. Difference

                                                           from point A to point F' and to F is 8 3 = 5 units.
                                                           Define some other point that is different from

                                                           the point F' and to F is 5 units. Dotted

                                                           relationship to form a hyperbola. So, the
                       hyperbola is the locus of the points. the point where the difference between the two

                       points is fixed is the same. The two fixed points are called the focus and the
                       difference in the same distance is expressed by 2a.
















                       Suppose that the point   (  0,   0) is a point that lies on hyperbole. By definition we

                       get      −       =  2  .
