1 . 求作一个立方体,使其体积等于已知立方体体积的2倍,这就是历史上有名的立方倍积问题.1837年法国数学家闻脱兹尔证明了立方倍积问题不能只用直尺与圆规作图来完成,不过人们发现,跳出直尺与圆规作图的框框,可以找到不同的作图方法.如图是柏拉图(公元前427—公元前347年)的方法:假设已知立方体的边长为
,作两条互相垂直的直线,相交于点
,在一条直线上截取
,在另一条直线上截取
,在直线
上分别取点
,使
(只要移动两个直角尺,使一个直角尺的边缘通过点
,另一个直角尺的边缘通过点
,并使两直角尺的另一边重合,则两直角尺的直角顶点即为
),则线段
即为所求立方体的一边.以直线
、
分别为
轴、
轴建立直角坐标系,若圆
经过点
,则圆
的方程为______ .
