贵刊2014年第1期文[1]把2013年全国高考陕西卷解析几何试题进行拓广探究,得到了关于抛物线、圆、椭圆、双曲线的8个结论,读后颇受启发,但觉意犹未尽.本文拟对由这些该试题得到的结论进行再拓广探究,即把上述结论进行综合并加以推广.1结论的综合先把文[1]中关于抛物线、椭圆、双曲线的6个结论(圆可视为椭圆的特例,故文[1]中关于圆的结论3、6在这里从略)综合如下:
In your 2014 issue of the 1st issue, [1] explored the geometry analysis of the Shaanxi National College Entrance Examination in 2013, and obtained eight conclusions about parabola, circle, ellipse and hyperbola. This article intends to further explore the conclusions obtained from these questions, that is, to synthesize the above conclusions and generalize them. 1 General conclusions of the conclusions Six conclusions about the parabola, ellipse and hyperbola in the article [1] (The circle can be regarded as a special case of an ellipse. Therefore, the conclusions of the circle [3] and [3] in [1] are summarized here):
