函数作为高中数学的核心知识,始终贯穿于整个高中数学的教学过程中,而对于函数性质的应用,更是历年高考中的常规考点.在函数的诸多性质中,不得不提到的一类特殊函数就是奇函数.由于奇函数有着独特的简洁而又优美的性质,在解题中,通过奇函数的图像特征,巧用奇函数的定义与性质,往往会发挥出意想不到的效果,就像一把开启智慧的钥匙,瞬
Function as the core knowledge of high school mathematics, and always runs through the whole high school mathematics teaching process, and for the application of the nature of the function is more than the conventional entrance examination in the calendar year .In many of the nature of the function, I have to mention a special Function is an odd function. Since odd functions have unique and concise but graceful properties, in the solution of the problem, through the image features of odd functions, clever use of the definition and nature of odd functions, often will play an unexpected effect, like A key to open wisdom, instantaneous
