对于函数f(x)=Asin(ωx+φ)中的ω,同学们都知道它与函数的周期关系最密切,已知周期T可以求ω,利用零点的坐标或者极值点也可以求ω。但很多题目提供的信息却不一定是与它们有关,同学们做起来难以动手,下面看看各种题目是如何化解难点的。一、利用函数的周期求解 For ω in the function f(x)=Asin(ωx+φ), the students all know that it has the closest relationship with the periodicity of the function. The known period T can be found as ω. The zero point can also be used to find the coordinates or extreme points. . However, the information provided by many topics is not necessarily related to them. Students can hardly get started. Here is a look at how various topics solve difficult problems. First, use the cycle of the function to solve
