导数是高中数学的重要内容,也是高考考查的重点,它给我们解决复杂函数问题带来了很多的方便。为了培养同学们对导数的浓厚兴趣,今天就带大家深入了解导数。导数是微积分中的重要基础概念。当函数y=f(x)的自变量x在一点x_0上产生一个增量Δ_x时,函数输出值的增量Δ_y与自变量增量Δ_x的比值在Δ_x趋于0时的极限a如果存在,a即为y=f(x)在x_0处的导数,记作f′(x_0)。
Derivatives is an important part of high school mathematics, college entrance examination is also the focus of investigation, it gives us a lot of convenience to solve complex function problems. In order to cultivate the students’ strong interest in the derivative, we will take the lead in understanding the derivative today. Derivatives are important fundamental concepts in calculus. When an argument x of the function y = f (x) produces an increment Δ_x at a point x_0, the limit a of the ratio of the increment Δ_y of the function output to the increment Δ_x of the argument as Δx approaches 0, if present, a is the derivative of y = f (x) at x_0, denoted by f ’(x_0).
