| Abstract: | In our report,four methods of complete differential quadrature of function with three variables were introduced,the first one was performed with space curve integral;the second was to calculate the original function with indefinite integral;the third and the fourth were with improvising differentiation and separate differentiation during the subsection integral of complete differential equation.The feasibility of the four methods were demonstrated with examples. |
