数形结合在一类特殊曲线中的运用
Applications of Notion of Number-Shape Combination in a Class of Special Curves
摘要
Abstract
With the notion of number-shape combination,an interesting geometric problem is studied.When symmetric lens rotate a circle in the regular triangle,the solutions of the trajectory of its center and the area of planar region which the trajectory forms are obtained.关键词
