second partial derivative

基本解释

In this paper, the formula of partial derivative of second order on compound function of many varables is established.
本文建立了多元复合函数的二阶偏导数公式。
Based on it, the tabular methods calculating the first-order and second-order Boolean partial derivative of the OC type logic function were proposed.
在此基础上提出了计算OC型逻辑函数一阶、二阶布尔偏导数的表格方法。
The factor of the mixed partial derivative term controls the grid orthogonality. The other two factors of second order partial derivative terms control the grid spacing.
结果表明：方程中混合偏导数项系数具有控制网格正交性的作用；

So, using those, now, what happens if we take the second derivative of A, the mixed derivative, partial with respect to T and the partial with respect to V.
如果我取A的二阶导数,混合导数，对T偏微分,再对V偏微分。
