三角函数的最值问题是三角函数知识的综合应用,是对三角函数的概念、图像和性质,以及对诱导公式、同角三角函数基本关系式、两角和与差的三角函数公式的综合考查,是函数内容的交汇点,也是函数思想的具体体现.三角函数最值有着广泛的应用,是历届高考的重点,也是高考命题的热点.对这类问题,只要
The most significant problem of trigonometric functions is the comprehensive application of trigonometric function knowledge. It is a comprehensive examination of the concept, images and properties of trigonometric functions, as well as the trigonometric function formulas of induction formulas, trigonometric trigonometric functions, trigonometric functions and trigonometric functions , Is the function of the intersection of the content, but also a concrete manifestation of the function of thought.The trigonometric function has a wide range of applications, is the focus of previous college entrance examination, but also the hot topic college entrance examination .For such problems, as long as
