In Exploration 2.3.1 Part B, you derived the standard equation of an ellipse. P(x,y) F(0,c) l - directrix Suppose you have already established F to be the focus of the parabola and line I to be the directrix o the parabola. The coordinates of L can best be represented a v[ Select ] according to the (x,y) Figure above. After simplifying FP = PL ,t (x,-y) [ Select ) can be written as (x,c) (x,-c)
