在普通高中数学新课程人教版必修4P67,即第一章三角函数中“三角函数模型的简单应用”部分有这样一道例题:图1例1图例1如图1,某地一天从6时到14时的温度变化曲线近似满足函数y=Asin(ωx+φ)+b(A0,ω0).1)求这一天的最大温差;2)写出这段曲线的函数解析式.解1)由图1可知,这一天 In the ordinary new high school mathematics new course teaching edition required 4P67, namely the first chapter trigonometric function “the simple application of the trigonometric function model” section has such an example: Figure 1 Example 1 Figure 1 Figure 1, a day from 6 o’clock to The temperature change curve at 14 o’clock approximately satisfies the function y=Asin([omega]x+[phi])+b(A0,[omega]0).1) to find the maximum temperature difference of this day; 2) Write the function analytical formula of this curve. Solution 1) Figure 1 shows that this day
