Viewing the Importance of Parametric Equation and Polar Coordinates Form Computer Polting
LU Jing (School of Sciences, Hangzhou Teachers College, Hangzhou 310012, China)
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.
