三角函数的最值(值域)问题是每年高考重点考查的知识点之一,它不仅与三角函数自身的常见的基础知识密切相关,而且与数学中的其他有关知识有密切联系.而分式型三角函数的最值(值域)问题却是这类问题的难点,这类考题综合性强,解法灵活,对能力要求较高.本文通过对一道分式三角函数最值问题解法的探究,归纳总结这类问题的常见解法.
The question of the value of the trigonometric function (value range) is one of the most important points of the annual college entrance examination. It is not only closely related to the common basic knowledge of the trigonometric function itself, but also has a close relationship with other related knowledge in mathematics. The problem of the value of the trigonometric function (value range) is the difficulty of this type of problem. This type of problem has a strong comprehensiveness, a flexible solution method, and a high requirement for the ability. This paper explores the solution to the problem of a fractional trigonometric function. Summarize the common solution to this type of problem.
