解题方法
1 . 球面几何在研究球体定位等问题有重要的基础作用.球面上的线是弯曲的,不存在直线,连接球面上任意两点有无数条曲线,它们长短不一,其中这两点在球面上的最短路径的长度称为两点间的球面距离.
纬线,赤道以北叫做北纬.如图1,将地球看作球体,假设地球半径为
,球心为
,北纬
的纬线所形成的圆设为圆
,且
是圆
的直径,球面被经过球心
和点
,
的平面截得的圆设为圆
,求圆
中劣弧
的长度,并判断其是否是
,
两点间的球面距离(只需判断、无需证明).
(2)如图2,点
,
在球心为
的球面上,且
不是球的直径,试问
,
两点间的球面距离所在的圆弧
是否与球心
共面?若是,写出证明过程,并求出当
,
时,
,
两点间球面距离所在的圆弧
与球心
所形成的扇形
的面积;若不是,请说明理由.

8 . 水星是离太阳最近的行星,在地球上较难观测到.当地球和水星连线与地球和太阳连线的夹角达到最大时,称水星东(西)大距,这是观测水星的最佳时机(如图1).将行星的公转视为匀速圆周运动,则研究水星大距类似如下问题:在平面直角坐标系中,点A,
分别在以坐标原点
为圆心,半径分别为1,3的圆上沿逆时针方向做匀速圆周运动,角速度分别为
,
.当
达到最大时,称A位于
的“大距点”.如图2,初始时刻A位于
,
位于以
为始边的角
的终边上.
,当A第一次位于
的“大距点”时,A的坐标为______ ;
(2)在
内,A位于
的“大距点”的次数最多有______ 次
