1 . 已知勒洛四面体是一个非常神奇的“四面体”,它能在两个平行平面间自由转动,并且始终与两平面都接触,因此它能像球一样来回滚动(如图甲),利用这一原理,科技人员发明了转子发动机.勒洛四面体是以正四面体的四个顶点为球心,以正四面体的棱长为半径的四个球的相交部分围成的几何体(如图乙),若勒洛四面体ABCD能够容纳的最大球的表面积为
,则正四面体ABCD的内切球的半径为______ .

2 . 欧拉(1707-1783),他是数学史上最多产的数学家之一,他发现并证明了欧拉公式
,从而建立了三角函数和指数函数的关系,若将其中的
取作
就得到了欧拉恒等式
,它是令人着迷的一个公式,它将数学里最重要的几个量联系起来,两个超越数——自然对数的底数
,圆周率
,两个单位——虚数单位
和自然数单位
,以及被称为人类伟大发现之一的
,数学家评价它是“上帝创造的公式”,请你根据欧拉公式:
,解决以下问题:
(1)将复数
表示成
