The Ration Geometrical Characteristic of the Curvilinear Equation (a_1x+b_1y+c_1)(a_2x+b_2y+c_2)=1

文章用坐标平移与旋转方法,获得了曲线方程(a1x+b1y+c1)(a2x+b2y+c2)=1((a12+b12)(a22+b22)≠0(1)在xoy平面上的完全定量几何特征.由其特征,我们可以方便地给出它们的具体方程表示的曲线的重要参数.

Here we obtain the complete ration geometrical characteristic of the curvilinear equation in plane by using translation as their idiographic and rotation of axes, therefore we can show the important parameter of the curve equation conveniently. expressed
