在初中我们称5-12≈0·168为黄金分点,在解析几何中我们把离心率为5-12的椭圆叫做黄金椭圆.同样我们也将离心率为5+12的双曲线称为黄金双曲线.黄金椭圆和双曲线的性质很多,本文先谈谈黄金椭圆的性质再类比黄金双曲线的性质,以下用椭圆x2a2+y2b2=1(a0,b0)为例来说明.(1)如果椭 In the junior high school, we call 5-12≈0·168 as the golden point. In the analytic geometry, we call the ellipse with the eccentricity of 5-12 as the gold ellipse. Similarly, we also call the hyperbola with the eccentricity of 5+12 as gold. Hyperbola. There are many properties of gold ellipses and hyperbolas. This article first talks about the nature of the gold ellipse and the properties of the gold hyperbola. The following uses the ellipse x2a2+y2b2=1(a0,b0) as an example to illustrate. (1) If oval
