函数是数学中的核心内容,三角函数又是函数的重要组成部分,尤其三角函数的最值问题应用非常广泛,并与生活实际密切相关。三角函数的最值问题涉及内容广泛,解法灵活,解题过程中渗透多种数学思想,且学生解答时容易出错,为了引导学生准确掌握这部分知识,现结合高中数学课本中涉及的三角函数的最值问题进行归类探究,诱导学生掌握三角函数最值问题的解题策略. Function is the core of mathematics. Trigonometric function is an important part of function. In particular, the most value of trigonometric function is widely used and closely related to life. The most value of trigonometric functions involves a wide range of content, flexible solution, a variety of mathematical ideas in the process of solving problems, and students prone to error when answering, in order to guide students to accurately grasp this part of the knowledge, combined with trigonometric functions involved in high school math textbooks The most value of the problem of classification and inquiry to induce students to master the most value of the trigonometric function problem solving strategy.
