三角函数最值问题是三角函数中的重要知识点,也是高中数学中的重要内容之一.解决这类问题的基本途径,同求解其它函数最值一样,一方面充分利用三角函数自身的特殊性,另一方面还要将求解三角函数最值问
The most important problem with trigonometric functions is one of the important knowledge points in trigonometric functions and also one of the important contents in high school mathematics.The basic way to solve such problems is the same as solving other functions and make full use of the particularity of trigonometric functions , On the other hand will also solve the trigonometric function most asked
