【f(x)＝g(x)/x,x≠0；0,x＝0,其中g(x)可导,且在x＝0处二阶导数g#39;#39;(0)=3,且g(0)＝g#39;(0)＝0,试求f#39;(0)】
<p>问题：【f(x)＝g(x)/x,x≠0；0,x＝0,其中g(x)可导,且在x＝0处二阶导数g#39;#39;(0)=3,且g(0)＝g#39;(0)＝0,试求f#39;(0)】<p>答案：↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">古熙悠的回答：<div class="content-b">网友采纳 f'(0)=lim/x =lim/x =limg(x)/x² 洛必达法则 =limg'(x)/(2x) =(1/2)lim/x =(1/2)g''(0) =3/2 若有不懂请追问,如果解决问题请点下面的“选为满意答案”.
