引言在中学阶段,数形结合思想所占的地位非常重要,三角函数的学习引出了函数的周期性的学习,利用数形结合思想探讨函数的周期性,在实际解题过程中具有非常重要的作用。本文主要是对三角函数的周期性进行总结探讨,主要来源于实际题型。1y=Asin(ωx+φ)的周期课本上对y=Asin(ωx+φ)的周期求法进行了讲解,一般求其最小正周期,其公式为T=2π/|ω|,为我们研究这类函数最基本
INTRODUCTION In the middle school stage, the status of number combining thought is very important. The study of trigonometric function leads to the periodic learning of function, and discusses the periodicity of the function by the combination of number and form, which is very important in practical problem solving effect. This paper mainly summarizes the periodicity of trigonometric functions, mainly from the actual questions. 1y = Asin (ωx + φ) cycle textbook on the y = Asin (ωx + φ) of the cycle of the method were explained, the general seeking minimum positive period, the formula for T = 2π / | ω |, for our study of this The most basic type of function
