一、思入风云变态中让图形动起来,在动变中了解问题的来龙去脉,发现问题的内在联系与变化规律,灵活运用这些规律解决问题,看到知识的普遍联系. 例1 如图1,某地一天从6时至14时的温度变化曲线近似满足函数y=Asin(ωx+(?))+b,写出这段曲线的函数解析式. First, think about the situation in the metamorphosis let the graphics move, understand the ins and outs of the problem in the dynamic change, find the intrinsic relations and changes in the law, use these laws to solve problems, see the general connection of knowledge. Example 1 The temperature change curve of a place from 6 o’clock to 14 o’clock one day approximately satisfies the function y=Asin(ωx+(?))+b, and the function analytical formula of this curve is written.
