therefore, with DERVX you can only calculate derivatives with respect to X.

Some examples of first-order partial derivatives are shown next:

Higher-order derivatives

The following second-order derivatives can be defined

The last two expressions represent cross-derivatives, the partial derivatives signs

in the denominator shows the order of derivation. In the left-hand side, the

derivation is taking first with respect to x and then with respect to y, and in the

right-hand side, the opposite is true. It is important to indicate that, if a

function is continuous and differentiable, then
