资源描述

1、导数的运算法则,基本初等函数的导数公式:,导数的运算法则:,法则1:两个函数的和(差)的导数,等于这两个函数的导数的 和(差),即:,法则2:两个函数的积的导数,等于第一个函数的导数乘第二个函数,加上第一个函数乘第二个函数的导数 ,即:,法则3:两个函数的积的导数,等于第一个函数的导数乘第二个函数,减去第一个函数乘第二个函数的导数 ,再除以第二个函数的平方.即:,例1 求下列函数的导数:(1)y(x1)2(x1);(2)yx2sinx;,解析 (1)方法一:y(x1)2(x1)(x1)2(x1)2(x1)(x1)(x1)23x22x1.方法二:y(x22x1)(x1)x3x2x1,y(x3x2

2、x1)3x22x1.(2)y(x2sinx)(x2)sinxx2(sinx)2xsinxx2cosx.,点评 较为复杂的求导运算,一般综合了和、差、积、商的几种运算,要注意:(1)先将函数化简;(2)注意公式法则的层次性,(1)y =3x2 (2)y =4x9x (3) y =18x8x9 (4) y=11/2cosx,点评 不加分析,盲目套用求导法则,会给运算带来不便,甚至导致错误在求导之前,对三角恒等式先进行化简,然后再求导,这样既减少了计算量,也可少出差错,y1/2cosx.,补充练习:求下列函数的导数:,答案:,1、熟记基本函数的导数公式 2、掌握两个函数的和、差、积、商的求导法则 3、会求简单函数的导数,总结:,
