limx趋于∏sinx/(∏-x)我还没学过导数啊,
<p>问题:limx趋于∏sinx/(∏-x)我还没学过导数啊,<p>答案:↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">陈宏敏的回答:<div class="content-b">网友采纳 limsinx/(∏-x) =limcosx/(-1)洛必达法则,分子分母同时求导数 =-cos∏ =1 ----------------------- limsinx/(∏-x) =limsin(∏-x)/(∏-x) =1 x趋于∏,也就是∏-x趋于0,根据limsint/t=1得到
