函数的对称性、奇偶性是历年高考的重点,而它与其他函数性质的综合考查更是难点。在高考复习中应注重结合一些初等函数,特别是三角函数,来提高函数性质的综合应用能力。下面我们来谈谈利用导数转化函数的对称性。一、建构知识网络1.单个函数的对称性 Function symmetry, parity is the focus of the college entrance examination over the years, and it is a comprehensive examination of the nature of other functions is more difficult. In the college entrance examination review should focus on combining some elementary functions, especially trigonometric functions, to improve the function of the comprehensive application of the ability. Now let’s talk about the symmetry of using the derivative conversion function. First, the construction of knowledge networks 1. Symmetry of a single function
