函数f(x)=Asin(ωx+φ)的最值点是函数图象的关键点,它不仅在作函数图象时起重要作用,而且在研究函数的有关性质时经常用到.本文把它的几个常用性质加以归纳,并给出应用举例.
The point of the function f(x)=Asin(ωx+φ) is the key point of the function image. It not only plays an important role in the function image, but also is often used when studying the related properties of the function. It summarizes several common properties and gives examples of applications.
