分享兴趣,传播快乐,增长见闻,留下美好!亲爱的您,这里是LearningYard新学苑。今天小编为大家带来好学高数(三):函数的求导法则

Share interests, spread happiness, grow insights, and leave a good life! Dear you, this is the new Academy of LearningYard. Today Xiaobian brings you the good learning of high numbers (3): the law of differentiation of functions

导数的概念

1、当函数在某一点a的导数无穷大,则在a点不可导

2、可导一定连续,连续不一定可导

导数存在和导数连续的区别:

①满足条件不同

a、导数存在:只要存在左导数或者右导数就叫导数存在。

b、可导:左导数和右导数存在并且左导数和右导数相等才能叫可导。

②函数连续性不同

a、导数存在:导数存在的函数不一定连续。

b、可导:可导的函数一定连续;连续的函数不一定可导,不连续的函数一定不可导。

③曲线形状不同

a、导数存在:曲线是不连续的,存在尖点或断点。

b、可导:可导的曲线形状是光滑的,连续的。没有尖点、断点。

First, the derivative concept

1, when the derivative of the function at a point is infinite, it is not derivable at point a

2, derivable must be continuous, and the difference between the continuous and the derivative is not necessarily derivable:

1) the conditions are different

a, the derivative exists: as long as there is a left derivative or a right derivative, it is called the derivative existence. b. Derivable: The existence of the left and right derivatives and the equality of the left and right derivatives can be called derivable.

2) The function continuity is different

a、the derivative exists: the function in which the derivative exists is not necessarily continuous.

b. Derivable: the derivable function must be continuous; Continuous functions are not necessarily derivable, and discontinuous functions must not be derivable.

(3) The shape of the curve is different

a, the derivative exists: the curve is discontinuous, and there are sharp points or breakpoints.

b, conductive: the shape of the conductive curve is smooth and continuous. There are no sharp points, breakpoints.

求导法则

1、求导公式

a的无穷次方的导数,a的x次方高阶导数推导过程(2)

推导 例:

a的无穷次方的导数,a的x次方高阶导数推导过程(3)

2、反函数求导

反函数求导=原函数导数的倒数

3、复合函数求导

①主要思路:由外向内逐步求导

例:

a的无穷次方的导数,a的x次方高阶导数推导过程(4)

补充:

a的无穷次方的导数,a的x次方高阶导数推导过程(5)

Second, the law of differentiation

1, the derivative formula

2, the inverse function to derive the inverse function derivative = the reciprocal of the original function derivative

3, composite function derivation

(1) The main idea: from the outside to the inner step by step derivation
