| Abstract: | Differential element method of definite integral is very useful for calculating some geometrical or physical quanlities.But in general textbooks,the differential element condition of differential element method of definite integral is not described exactly in mathematical language.In this paper,a question is proposed by an interesting example and the condition of differential element and the explanation of the question is given in mathematical statement.The differential element method is applied to solve several relative geometric problems is presented. |
