multivariable function%extreme value%discriminance method
对于一般多元函数的极值，从全微分概念推出一种不必计算任何高阶偏导数的判别法，并用于解决一些问题。
對于一般多元函數的極值，從全微分概唸推齣一種不必計算任何高階偏導數的判彆法，併用于解決一些問題。
대우일반다원함수적겁치，종전미분개념추출일충불필계산임하고계편도수적판별법，병용우해결일사문제。
For the extreme value of the general multivariate function,introduced one method to discriminate the value, which is directly derived from the concept of the total differential and which does not require any calculation of partial derivative of higher order,and resolve some certain problemsit using the method.
