一、填空题
〔每题4分，共20分〕1．直线<Object: word/embeddings/oleObject1.bin>
过点<Object: word/embeddings/oleObject2.bin>
，且与平面
<Object: word/embeddings/oleObject3.bin>
垂直，那么该直线的方程
是．2．设曲面<Object: word/embeddings/oleObject4.bin>
上点<Object: word/embeddings/oleObject5.bin>
处的切平面平行于平面
<Object: word/embeddings/oleObject6.bin>
，那么点<Object: word/embeddings/oleObject7.bin>
的坐标是．3．设<Object: word/embeddings/oleObject8.bin>
：<Object: word/embeddings/oleObject9.bin>
，<Object: word/embeddings/oleObject10.bin>
在<Object: word ...
