曲线对称性的解析研究河南省教育出版社张国旺天津市宝坻县教研室杨之一、问题和引理奇、偶函数的图象，是极为特殊的对称图形（仅以原点为对称中心，仅以ｙ轴为对称轴），一般曲线则需经坐标轴平移、旋转才能判别其对称性．方程具有什么样的特征，其曲线具有对部性？怎样... Analysis of the symmetry of the curve Henan Province Education Press Zhang Guowang Tianjin Baodi County Teaching Research Office Yang one, problem and lyrical odd, even function of the image, is a very special symmetrical figure (only the origin as the center of symmetry, only y The axis is the axis of symmetry. The general curve must be translated and rotated by the coordinate axis to determine its symmetry. What kind of characteristics does the equation have, and the curve has some characteristics? how...
