## Using of Infinitesimal Substitution Method in Solution of Limit

HE Dong-mei 1,CHEN Wen hua 2,WANG Bian-jiang1(1.Mathematics department,2.Biology and chemistry department, Baoshan college,Baoshan Yunnan 678000 China)
In this paper,method about solution of the indeterminate expression(type)was discussed.The solution for limit of some indeterminate expressions may be simplified by correctly used infinitesimal substitution.But some details should be take care to avoid make mistake in using such method.
