新教材中新增的导数这部分内容,为高中数学注入了新的活力,因此导数的应用必将成为高考的热点,那么培养学生运用导数的意识解题则成为复习的一个焦点.镜头一:正确理解导数概念本身的实际意义——求变化率如曲线y=f(x)在给定点M(x0,y0)处的切线l的斜率k=f(x0)等.【例1】确定抛物 This new part of the new textbook’s derivative content has injected new vitality into high school mathematics. Therefore, the application of derivatives will become a hot spot for the college entrance examination. Therefore, the problem of cultivating students’ conscious use of derivatives is becoming a focus of review. Lens 1: Correctly understand the actual meaning of the derivative concept itself - find the rate of change such as the slope of the tangent line l at the given point M (x0, y0) of the curve y = f (x) k = f (x0), etc. [Example 1] Determine parabolic
