圆锥曲线大多有着良好的对称性,涉及到它们的诸多问题中,含有对称性的某些元素发生变化时往往伴随着有些固定的东西呈现,例如符合条件的曲线过定点,符合条件的点在某条直线或曲线上,或符合条件的式子为定值等等,这就是对称的美回馈一份定性的美。本文试图以椭圆和圆为例,对一些含对称的元素在运动中所涉及的定值、定形等加以粗浅的探讨,同时对问题的解决所涉及的
Most of the conic curves have good symmetry. Of the many problems involving them, some of the elements that contain symmetry tend to be accompanied by some fixed things, for example, the curve that meets the conditions passes through a fixed point, and the points that meet the requirements are in certain A straight line or curve, or the formula is consistent with the conditions for the value, etc., which is symmetrical beauty feedback a qualitative beauty. This paper attempts to ellipse and circle as an example, some symmetry elements involved in the movement of the value, shape and so on to be discussed shallowly, and the solution to the problem involved
