1、 14.导 数知识要点1.导数（导函数的简称）的定义：设0 x是函数)(xfy定义域的一点，如果自变量x在0 x处有 增 量x，则 函 数 值y 也 引 起 相 应 的 增 量)()(00 xfxxfy；比 值xxfxxfxy)()(00称为函数)(xfy在点0 x到xx0之间的平均变化率；如果极限xxfxxfxyxx)()(limlim0000存在，则称函数)(xfy在点0 x处可导，并把这个极限叫做)(xfy在0 x处的导数，记作)(0 xf或0|xxy，即)(0 xf=xxfxxfxyxx)()(limlim0000.注：x是增量，我们也称为“改变量”，因为x 可正，可负，但不为零.以知

2、函数)(xfy定义域为A，)(xfy的定义域为B，则 A与 B 关系为BA.2.函数)(xfy在点0 x处连续与点0 x处可导的关系：函数)(xfy在点0 x处连续是)(xfy在点0 x处可导的必要不充分条件.可以证明，如果)(xfy在点0 x处可导，那么)(xfy点0 x处连续.事实上，令xxx0，则0 xx相当于0 x.于是)()()(lim)(lim)(lim0000000 xfxfxxfxxfxfxxxx).()(0)()(limlim)()(lim)()()(lim0000000000000 xfxfxfxfxxfxxfxfxxxfxxfxxxx如果)(xfy点0 x处连续，那么)(

3、xfy在点0 x处可导，是不成立的.例：|)(xxf在点00 x处连续，但在点00 x处不可导，因为xxxy|，当x0 时，1xy；当x 0 时，1xy，故xyx0lim不存在.注：可导的奇函数函数其导函数为偶函数.可导的偶函数函数其导函数为奇函数.导数导数的概念导数的运算导数的应用导数的几何意义、物理意义函数的单调性函数的极值函数的最值常见函数的导数导数的运算法则3.导数的几何意义：函数)(xfy在点0 x处的导数的几何意义就是曲线)(xfy在点)(,(0 xfx处的切线的斜率，也 就 是 说，曲 线)(xfy在 点P)(,(0 xfx处 的 切 线 的 斜 率 是)(0 xf，切 线 方

4、程 为).)(00 xxxfyy4.求导数的四则运算法则：)(vuvu)(.)()()(.)()(2121xfxfxfyxfxfxfynn)()(cvcvvccvuvvuuv（c为常数）)0(2vvuvvuvu注：vu,必须是可导函数.若两个函数可导，则它们和、差、积、商必可导；若两个函数均不可导，则它们的和、差、积、商不一定不可导.例如：设xxxf2sin2)(，xxxg2cos)(，则)(),(xgxf在0 x处均不可导，但它们和)()(xgxfxxcossin在0 x处均可导.5.复合函数的求导法则：)()()(xufxfx或xuxuyy复合函数的求导法则可推广到多个中间变量的情形.6.

5、函数单调性：函数单调性的判定方法：设函数)(xfy在某个区间内可导，如果)(xf0，则)(xfy为增函数；如果)(xf0，则)(xfy为减函数.常数的判定方法；如果函数)(xfy在区间I内恒有)(xf=0，则)(xfy为常数.注：0)(xf是 f（x）递增的充分条件，但不是必要条件，如32xy在),(上并不是都有0)(xf，有一个点例外即x=0 时 f（x）=0，同样0)(xf是 f（x）递减的充分非必要条件.一般地，如果 f（x）在某区间内有限个点处为零，在其余各点均为正（或负），那么f（x）在该区间上仍旧是单调增加（或单调减少）的.7.极值的判别方法：（极值是在0 x附近所有的点，都有)(

6、xf)(0 xf，则)(0 xf是函数)(xf的极大值，极小值同理）当函数)(xf在点0 x处连续时，如果在0 x附近的左侧)(xf0，右侧)(xf0，那么)(0 xf是极大值；如果在0 x附近的左侧)(xf0，右侧)(xf0，那么)(0 xf是极小值.文档编码:CV9O7B3P5T10 HN6Q1M9U4N1 ZH5C5O8Y6L4文档编码:CV9O7B3P5T10 HN6Q1M9U4N1 ZH5C5O8Y6L4文档编码:CV9O7B3P5T10 HN6Q1M9U4N1 ZH5C5O8Y6L4文档编码:CV9O7B3P5T10 HN6Q1M9U4N1 ZH5C5O8Y6L4文档编码:CV9O
