从计算机作图看参数方程极坐标的重要性

Viewing the Importance of Parametric Equation and Polar Coordinates Form Computer Polting

在中学数学教学中,有关参数方程与极坐标的知识没有引起足够重视,进而使得了大一年级学生在这方面的能力不足,不能解有关的问题,计算机的使用也受到影响。在此,通过计算机作图,说明了参数方程极坐标的重要作用。

Since we do not pay more attention to the parametric equation and the polar coordinates in the middle school Maths teaching,we just mention them, without teaching them systematically. This greatly effects the freshmen's ability on these subjects. They can not solve problems involving these subjects, and can not use computer properly. Through computer polting, we try to explain the importance of parametric equation and the polar coordinates.
