二元函数的全微分求积

Quadrature of Complete Differential for Dualistic Functions

介绍了二元函数全微分求积的3种不同方法:利用平面上曲线积分的求法、利用不定积分求出原函数的方法和利用全微分方程求解的方法。用实例证明了3种方法的可行性。

This paper introduces three different methods,the method using quadrature of curves on planes,the method using indefinite quadrature to get original functions and the method using complete differential equations,to get the quadrature of the complete differential for dualistic functions.The examples in this paper prove the feasibility of those three methods.
