一、填空题（本题共6小题，每小题4分，满分24分. 把答案填在题中横线上）

1（1） lim(cosx)ln(1?x) =

x?0?21e .

g(x)【分析】 1型未定式，化为指数函数或利用公式limf(x)计算求极限均可.

1(1?)=elim(f(x)?1)g(x)进行

【详解1】 lim(cosx)x?0ln(1?x)2=ex?0ln(1?x2)lim1lncosx,

?sinxlncosxlncosxcosx??1， ?lim?lim而 limx?0ln(x?02x21?x2)x?0x2故 原式=e?12?1e.

12x12??， 2x2【详解2】 因为 lim(cosx?1)?x?01?limln(1?x2)x?0?所以 原式=e?12?1e.

【评注】 本题属常规题型，完全类似例题见《数学复习指南》P.24-25 【例1.30-31】.

22（2） 曲面z?x?y与平面2x?4y?z?0平行的切平面的方程是

2x?4y?z?5.

【分析】 待求平面的法矢量为n?{2,4,?1}，因此只需确定切点坐标即可求出平面方

22程, 而切点坐标可根据曲面z?x?y切平面的法
