SUMMARY
The transformation rule for vector-covector derivatives is established through the application of the chain rule and the properties of partial derivatives. Specifically, when differentiating a covector \( A_a \) with respect to coordinates \( x^b \), the terms involving mixed partial derivatives, such as \( \frac{\partial^2 f}{\partial x \partial y} - \frac{\partial^2 f}{\partial y \partial x} \), vanish, confirming the correct transformation behavior. The key to resolving the issue lies in correctly applying the transformation rules for vectors and covectors and ensuring differentiation is performed in the appropriate coordinate system.
