型抛物线图象.发现:如图1所示,该类型图象上任意一点M到定点
的距离
,始终等于它到定直线
上的距离
(该结论不需要证明),他们称:定点F为图象的焦点,定直线l为图象的准线,
叫做抛物线的准线方程.其中原点O为

,准线方程为
.其中
.
(1)【基础训练】请分别直接写出抛物线
的焦点坐标和准线l的方程;
(2)【技能训练】如图2所示,已知抛物线
上一点P到准线l的距离为6,求点P的坐标;
(3)【能力提升】如图3所示,已知过抛物线
的焦点F的直线依次交抛物线及准线l于点
,若
求a的值;
(4)【拓展升华】古希腊数学家欧多克索斯在深入研究比例理论时,提出了分线段的“中末比”问题:点C将一条线段
分为两段
和
,使得其中较长一段
是全线段
与另一段
的比例中项,即满足:
,后人把
这个数称为“黄金分割”,把点C称为线段
的黄金分割点.如图4所示,抛物线
的焦点
